# Find the Lcm and Hcf of the Following Integers by Applying the Prime Factorisation Method: 8, 9 and 25 - Mathematics

Numerical

Find the LCM and HCF of the following integers by applying the prime factorisation method:

8, 9 and 25

#### Solution

8, 9 and 25

Let us first find the factors of 8,9 and 25

8=2^2

9=3^3

25=5^2

L.C.M of 8,9 and 25 =2^2xx3^2xx5^2

L.C.M of 8,9 and 25 = 1800

H.C.F of 8,9 and 25 =1
