Given numbers are 128,836,803,816

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

The LCM of 128,836,803,816 is 99597696.

Find LCM of 128,836,803,816 with Prime Factorization

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

2 x 2 x 2 x 2 x 11 x 8 x 19 x 73 x 51 = 99597696

Therefore, the lowest common multiple of 128,836,803,816 is 99597696.

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.

128 x 836 x 803 x 816 = 70116777984

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.

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

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

803 : 1, 11, 73, 803

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,836,803,816, is 1.

Now, the common factors can be found like this.

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

836:2x 2x 11x 19

803:11x 73

816:2x 2x 2x 2x 3x 17

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 2x 2x 11 = 704

Therefore, the value for common factors is 704.

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 = 70116777984/(1x704)

LCM = 70116777984/704

LCM = 99597696

Thus, we can understand that the LCM of 128,836,803,816 is 99597696.
