Question

What is the l.c.m of 22,18,16 step by step

Answer 1

Answer:

Step-by-step explanation:

By prime factorization

16 = 2 × 2 × 2 × 2

18 = 2 × 3 × 3

22 = 2 × 11

HCF ( 16, 18, 22 ) = 2

LCM ( 16, 18 ) = 2 × 2 × 2 × 2 ×3 × 3 = 144

By prime factorization

22 = 2 × 11

144 = 2 × 2 × 2 × 2 × 3 × 3

HCF = 2 ( as before )

Lcm = 2 × 2 × 2 × 2 × 3 × 3 × 11 = 1584

Lcm ( 16, 18, 22 ) = 1584

Hope this helps you
