Question

Find the least common multiple of 18 ,12 , and .14

Answer 1

First, factor all these numbers:

• 18=2·3·3;
• 12=2·2·3;
• 14=2·7.

Then

• find all common factors for three numbers - this is factor 2 and write it as first factor of LCM(18,12,14);
• find all common factors for two numbers - this is factor 3 and write it as second factor of LCM(18,12,14);
• write all remaining factors.

At last, the least common multiple LCM(18,12,14)=2·3·3·2·7=252.

Answer: 252.

Answer 2

Hello!
I'm assuming that the values you gave are 18, 12 and 14, but there's a period before the 14, I think that's a mistake but if it's not please let me know, anyhow, the least common multiple of 12, 14 and 18 is 252.

Good luck!
