LCM is 21, which is the multiple of the highest power of prime factors in the given numbers (3 x 7).
The LCM is 21.
The least common denominator would be 7. So the if it were a fraction being reduced. Seven goes into seven one time and seven goes into twenty-one three. So the fraction would be 3/1.
the lcm of 3 and 7 is 21 and the lcm of 7 and 21 is 21, so the lcm of 3, 7 and 21 is the lcm of 21 and 21 which is 21.
The LCM is 105.
The LCM is 42
The LCM is 84.
LCM of 5 7 21 is 105.
The LCM of 7 21 35 is 105
The LCM is 252.
The LCM is 42.
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
LCM(21, 7) = 21
21 is the LCM of 3 and 7
