Question

1. Find the LCM of smallest two digit composite number and smallest single digit composite number​

Answer 1

Smallest 2 digit Composite no. is 10

smallest Single digit Composite no. is 4

$Facter \: of \: 4 \: and \: 10 \: \\ 4 = 1 \times 2 \times 2 \\ 10 = 1 \times 2 \times 5$

So

LCM of (4,10) is 2 × 2 × 5 = 20

$\;\large{\boxed{\bf{\purple{LCM (4,10) = 20}}}}$
