Given numbers are 861,862,998,776

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

The LCM of 861,862,998,776 is 143695341384.

Find LCM of 861,862,998,776 with Prime Factorization

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

2 x 861 x 431 x 499 x 388 = 143695341384

Therefore, the lowest common multiple of 861,862,998,776 is 143695341384.

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.

861 x 862 x 998 x 776 = 574781365536

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

862 : 1, 2, 431, 862

998 : 1, 2, 499, 998

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,862,998,776, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

862:2x 431

998:2x 499

776:2x 2x 2x 97

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 = 574781365536/(1x4)

LCM = 574781365536/4

LCM = 143695341384

Thus, we can understand that the LCM of 861,862,998,776 is 143695341384.
