Given numbers are 676,990,877,455,728

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

The LCM of 676,990,877,455,728 is 4108464360.

Find LCM of 676,990,877,455,728 with Prime Factorization

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

2 x 2 x 5 x 7 x 13 x 1 x 99 x 877 x 13 x 2 = 4108464360

Therefore, the lowest common multiple of 676,990,877,455,728 is 4108464360.

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 990 x 877 x 455 x 728 = 194412533515200

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

877 : 1, 877

455 : 1, 5, 7, 13, 35, 65, 91, 455

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,990,877,455,728, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

990:2x 3x 3x 5x 11

877:877

455:5x 7x 13

728:2x 2x 2x 7x 13

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 5x 7x 13x 13 = 47320

Therefore, the value for common factors is 47320.

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 = 194412533515200/(1x47320)

LCM = 194412533515200/47320

LCM = 4108464360

Thus, we can understand that the LCM of 676,990,877,455,728 is 4108464360.
