→ □ FOR LCM
To get the Least Common Multiple (LCM) of 220 and 264 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
220: 2 2 5 11
264: 2 2 2 3 11
LCM: 2 2 2 3 5 11
The Least Common Multiple (LCM) is: 2 x 2 x 2 x 3 x 5 x 11 = 1320■
→ □ FOR HCF
Find the prime factorization of 220
220 = 2 × 2 × 5 × 11
Find the prime factorization of 264
264 = 2 × 2 × 2 × 3 × 11
To find the HCF, multiply all the prime factors common to both numbers:
Therefore, HCF = 2 × 2 × 11
HCF = 44■
