Factors of any number are the whole numbers that can divide the number completely. Why are factors important to learn? For mathematical approaches, factors are used in organizing and bringing more efficiency to any task. In this article, let's learn how to solve factors of 76 easily.
Factors of 76 are those numbers that can divide 76 perfectly. The factors of 76 are:
1,2,4,19,38 and 76.
Negative factors of 76: -1, -2, -4, -19, -38, -76
Prime factors of 76: 2
Prime factorization of 76: 22×19
The sum of factors of 76: 1+2+4+19+38+76= 140
For finding factors of 76, we will be learning these below-mentioned methods:
This particular method often finds the pair of factors which, on multiplication together, produces 76. Let us find the pairs which, on multiplication, yields 76.
1×76=76
2×38=76
4×19=76
From this, we conclude that, factors of 76 are:1,2,4,19,38 and 76.
The division method finds the numbers that evenly divides the given number 76. To find the factors of 76, we have to divide 76 by all possible natural numbers less than 76 and check.
1,2,4,19,38 and 76 are the only factors that the number 76 has. So to verify the factors of 76 using the division method, we just need to divide 76 by each factor.
76/1 =76
76/2 =38
76/4=19
76/19=4
76/38=2
76/76=1
Prime Factorization is the easiest process to find prime factors. It decomposes 76 into a product of its prime integers.
The number 76 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 76.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 76 are 2 and 38, then proceeding to 38, we get 2 and 19.
Factor Pairs:
Positive pair factors: (1,76), (2,38), (4,19)
Negative pair factors: (-1,-76), (-2,-38), (-4,-19).
Children quite often make silly mistakes while solving factors. Let us see what are the common errors to occur and how to avoid them.
Find the GCF of 76 and 72
Factors of 76: 1,2,4,19,38,76
Factors of 72: 1,2,3,4,6,8,9,12,18,24,36,72
Common factors of 76 and 72: 1,2,4
So, the Greatest Common Factor of 76 and 72 is 4.
Answer: 4
We first listed out the factors of 76 and 72 and then found the common factors and then identified the greatest common factor from the common list.
Find the LCM of 76 and 70
Prime factorization of 76: 22×19
.
Prime factorization of 70: 2×5×7
LCM of 70 and 76: 22×19×5×7= 2660.
Answer: 2660
Did prime factorization of both 70 and 76. The LCM is the product of the highest power of each factor.
The area of a rectangle is 76 square units. If the length is 19 units, then what is the measure of its width?
Area of rectangle: 76 sq units
Factors of 76: 1,2,4,19,38,76
We know that the area of a rectangle is the product of its length and breadth.
Given, length= 19 units
There exists a factor pair of 76, which is (4,19). Hence, width is 4 units. Let’s check it through the formula for area.
So, length×width = area
⇒ 19 × width = 76
⇒ width = 76/19 = 4
Answer: 4 units
Used the concept of factor pairs for 76 and rechecked using the formula for finding area of a rectangle.
Find the smallest number that is divisible by 2,4,19.
Prime factorization of 2: 2×1
.
Prime factorization of 4: 22
Prime factorization of 19: 19×1
LCM of 2,4,19: 22×19 = 76
Answer: 76 is the smallest number which is divisible by 2,4,19.
To find the smallest number which is divisible by 2,4,19, we need to find the LCM of these numbers.
What is the sum of the factors of 76 and 75?
Factors of 76: 1,2,4,19,38,76
Sum of the factors: 1+2+4+19+38+76= 140
Factors of 75: 1,3,5,15,25,75
Sum of the factors: 1+3+5+15+25+75 =124
Added all the factors togather to find the sum.
