The factors of the 4   :   1 , 2 , 4

The factors of the 22 :    1 , 2 , 11 , 22

The Greatest common factor (GCF) of two numbers 4 and 22 : 2

Formula is LCM * GCF = The product of numbers

Substitute GCF = 2 and the numbers are 4 , 22

LCM * 2 = 4 * 22

Divide each side by 2

Therefore LCM = (4 * 22) / 2

LCM = 44

The least common multiple (LCM) = 44

List the prime factor of each number

22 = 2 x 11 = 21 x 111

4 = 2 x 2 = 22

multiply the highest power in either factorization.

LCM = 22 * 111 = 44

least common multiple of 22 and 4 is 44

Least - common - multiple(4, 22)

image

L.C.M(4, 22) = 2 * 2 * 11

                     = 22 * 111

                     = 4 * 11

                     = 44.

Least - common - multiples of 4 and 22 is 44.

Least - common - multiple is the smallest(non - zero) number, that is a multiple of two or more numbers.

Multiples of 4 = 4, 8, 12, 16, 20, .......40, 44, 48, ............

Multiples of 22 = 22, 44, 66, 88, ...................

The smallest of the common multiples is 44.

So, the least - common - multiple of 4 and 22 is 44.
