Given numbers are 418,695,920,650,641

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

The LCM of 418,695,920,650,641 is 1113577121800.

Find LCM of 418,695,920,650,641 with Prime Factorization

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

2 x 5 x 209 x 139 x 92 x 65 x 641 = 1113577121800

Therefore, the lowest common multiple of 418,695,920,650,641 is 1113577121800.

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.

418 x 695 x 920 x 650 x 641 = 111357712180000

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

695 : 1, 5, 139, 695

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,695,920,650,641, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

695:5x 139

920:2x 2x 2x 5x 23

650:2x 5x 5x 13

641:641

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 111357712180000/(1x100)

LCM = 111357712180000/100

LCM = 1113577121800

Thus, we can understand that the LCM of 418,695,920,650,641 is 1113577121800.
