Given numbers are 776,398,392,821

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

The LCM of 776,398,392,821 is 6212323096.

Find LCM of 776,398,392,821 with Prime Factorization

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

2 x 2 x 2 x 97 x 199 x 49 x 821 = 6212323096

Therefore, the lowest common multiple of 776,398,392,821 is 6212323096.

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.

776 x 398 x 392 x 821 = 99397169536

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.

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

398 : 1, 2, 199, 398

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,398,392,821, is 1.

Now, the common factors can be found like this.

776:2x 2x 2x 97

398:2x 199

392:2x 2x 2x 7x 7

821:821

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 2 = 16

Therefore, the value for common factors is 16.

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 = 99397169536/(1x16)

LCM = 99397169536/16

LCM = 6212323096

Thus, we can understand that the LCM of 776,398,392,821 is 6212323096.
