Given numbers are 634,864,220,771,689

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

The LCM of 634,864,220,771,689 is 2667399340320.

Find LCM of 634,864,220,771,689 with Prime Factorization

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

2 x 2 x 3 x 317 x 72 x 55 x 257 x 689 = 2667399340320

Therefore, the lowest common multiple of 634,864,220,771,689 is 2667399340320.

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.

634 x 864 x 220 x 771 x 689 = 64017584167680

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.

634 : 1, 2, 317, 634

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

771 : 1, 3, 257, 771

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,864,220,771,689, is 1.

Now, the common factors can be found like this.

634:2x 317

864:2x 2x 2x 2x 2x 3x 3x 3

220:2x 2x 5x 11

771:3x 257

689:13x 53

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 3 = 24

Therefore, the value for common factors is 24.

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 = 64017584167680/(1x24)

LCM = 64017584167680/24

LCM = 2667399340320

Thus, we can understand that the LCM of 634,864,220,771,689 is 2667399340320.
