Answers
MathMate
60=<b>2^2</b>*3*<b>5</b>
126=2*<b>3^2</b>*<b>7</b>
The LCM is therefore
LCM=2^2*3^2*5*7
=1260
Alternatively you find it by division:
2 | 60, 126
3 | 30, 63
1 | 10, 21
LCM = 2*3*1*10*21 = 1260
126=2*<b>3^2</b>*<b>7</b>
The LCM is therefore
LCM=2^2*3^2*5*7
=1260
Alternatively you find it by division:
2 | 60, 126
3 | 30, 63
1 | 10, 21
LCM = 2*3*1*10*21 = 1260
