Given numbers are 676,690,128,995,988

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

The LCM of 676,690,128,995,988 is 28217754240.

Find LCM of 676,690,128,995,988 with Prime Factorization

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

2 x 2 x 5 x 13 x 13 x 69 x 32 x 199 x 19 = 28217754240

Therefore, the lowest common multiple of 676,690,128,995,988 is 28217754240.

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.

676 x 690 x 128 x 995 x 988 = 58692928819200

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

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

995 : 1, 5, 199, 995

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,690,128,995,988, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

690:2x 3x 5x 23

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

995:5x 199

988:2x 2x 13x 19

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 5x 13 = 2080

Therefore, the value for common factors is 2080.

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 = 58692928819200/(1x2080)

LCM = 58692928819200/2080

LCM = 28217754240

Thus, we can understand that the LCM of 676,690,128,995,988 is 28217754240.
