Given numbers are 974,780,616,851

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

The LCM of 974,780,616,851 is 49782172440.

Find LCM of 974,780,616,851 with Prime Factorization

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

2 x 2 x 487 x 195 x 154 x 851 = 49782172440

Therefore, the lowest common multiple of 974,780,616,851 is 49782172440.

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.

974 x 780 x 616 x 851 = 398257379520

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.

974 : 1, 2, 487, 974

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,780,616,851, is 1.

Now, the common factors can be found like this.

974:2x 487

780:2x 2x 3x 5x 13

616:2x 2x 2x 7x 11

851:23x 37

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 2 = 8

Therefore, the value for common factors is 8.

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 = 398257379520/(1x8)

LCM = 398257379520/8

LCM = 49782172440

Thus, we can understand that the LCM of 974,780,616,851 is 49782172440.
