Question

Find hcf and lcm of 20,25,50,100

Answer 1

Answer:

LCM = 100 and HCF = 10

Step-by-step explanation:

Factors of 20 = 2 × 2 × 5

Factors of  25 = 5 × 5

Factors of 50 = 5 × 5 × 2

Factors of 100 = 5 × 5 × 2 × 2

LCM(20, 25, 50,100) = 2² × 5² = 4 × 25 = 100

HCF(20, 25, 50,100) = 5 × 2 = 10

Therefore, the LCM and HCF of the given numbers are 100 and 10 respectively.

Hope this helps you !!!!
