Given numbers are 620,107,428,896

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

The LCM of 620,107,428,896 is 14860160.

Find LCM of 620,107,428,896 with Prime Factorization

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

2 x 2 x 107 x 155 x 1 x 1 x 224 = 14860160

Therefore, the lowest common multiple of 620,107,428,896 is 14860160.

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.

620 x 107 x 428 x 896 = 25440593920

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

107 : 1, 107

428 : 1, 2, 4, 107, 214, 428

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,107,428,896, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

107:107

428:2x 2x 107

896:2x 2x 2x 2x 2x 2x 2x 7

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

2x 2x 2x 2x 107 = 1712

Therefore, the value for common factors is 1712.

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 = 25440593920/(1x1712)

LCM = 25440593920/1712

LCM = 14860160

Thus, we can understand that the LCM of 620,107,428,896 is 14860160.
