LCM of 25 and 50 solved examples
Problem 1
The HCF between 25 and 50 is 5. What will be the LCM of 25 and 50 when prime factorization is used?
The LCM of 25 and 50 using the prime factorization method is 50
Explanation
To find the LCM of 25 and 50 using the prime factorization, list down the prime factors of 25 and 50. From the prime factors of each number, take the prime factor with the highest power, that is 21 and 52. Now multiply these to get 60 as the LCM
Problem 2
The LCM of 25 and b is 50. What is the value of ‘b’?
The value of ‘b’ is 50
Explanation
We know that the LCM of (25,b) is 50
According to the LCM formula, LCM(a, b) = a × b/HCF(a, b)
50 = 25 × b/HCF(25,b)
B = 50 x HCF(25,b)/25
b=50
Problem 3
The LCM of a and b is 50 and their HCF is 5, what is the product of a and b?
Answer : 1250
Explanation
LCM(a,b)×HCF(a,b) =a×b
LCM = 50
HCF = 25
50 × 25 = 50 × 25=1250
