Question

find the hcf and lcm of 234 ;572

Answer 1

234:   2 ×3×3×13
572:   2×2×11×13
LCM:   2(two times) ×3(two times) ×11 (one time )×13 (one time)

The Least Common Multiple (LCM) is:   2 x 2 x 3 x 3 x 11 x 13 = 5148

GCF: 2 and 13 are the common then
The Greates Common Factor (GCF) is:   2 x 13 = 26

Answer 2

Answer:

The HCF and LCM are 26 and 5148.      

Step-by-step explanation:

We have to find the LCM and HCF of 234 and 572.

The HCF i.e highest common factor is found by multiplying all the factors which appear in both numbers.

The LCM i.e lowest common multiple is found by multiplying all the factors which appear in either two.

The prime factorization of 234 and 572 is

$234=2\times 3\times 3\times 13$

$572=2\times 2\times 11\times 13$

$HCF=2\times13=26$

$LCM=2\times 3\times 2\times 3\times 11\times 13=5148$

The HCF and LCM are 26 and 5148.
