LCM OF 13 AND 18

Answer 1

234

M13 = {13,26,39,52,65,78,91,104,117,130,143,156,169,182,195,208,221,234,......}

M18 = {18,36,54,72,90,108,126,144,162,180,198,216,234,.......}

Therefore LCM (13,18) = 234. That is,234 is the least number they have in common.

When it gets tough, you can multiply the two numbers... 13*18 = 234. But always try to use my technique above.

Multiple of a is a*n where n is a natural number 1,2,3,4,......,and a is an integer.
