Question

Find the least common multiple ( LCM) by listing the multiples .

$10$ and $12$

Answer 1

Given, the numbers are $10$ and $12$

The multiples of $10$ are $=10,20,30,40,50,\mathbf{}\mathbf{60}\mathbf{},70,80,90,100,.......$

The multiples of $12$ are $=12,24,36,48,\mathbf{}\mathbf{60},72,\mathbf{}84,........$

The common multiples of $10$ and $12$ are $=60,120,180,240,.....$

Hence , the required LCM of $10$ and $12$ is $60$ .
