Given numbers are 989,119,128,908,715

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 989,119,128,908,715 is 2445035232640.

Find LCM of 989,119,128,908,715 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 989 x 119 x 32 x 227 x 715 = 2445035232640

Therefore, the lowest common multiple of 989,119,128,908,715 is 2445035232640.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

989 x 119 x 128 x 908 x 715 = 9780140930560

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

989 : 1, 23, 43, 989

119 : 1, 7, 17, 119

128 : 1, 2, 4, 8, 16, 32, 64, 128

908 : 1, 2, 4, 227, 454, 908

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,119,128,908,715, is 1.

Now, the common factors can be found like this.

989:23x 43

119:7x 17

128:2x 2x 2x 2x 2x 2x 2

908:2x 2x 227

715:5x 11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 9780140930560/(1x4)

LCM = 9780140930560/4

LCM = 2445035232640

Thus, we can understand that the LCM of 989,119,128,908,715 is 2445035232640.
