Given numbers are 920,991,518,863,638

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

The LCM of 920,991,518,863,638 is 65007389237560.

Find LCM of 920,991,518,863,638 with Prime Factorization

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

2 x 460 x 991 x 259 x 863 x 319 = 65007389237560

Therefore, the lowest common multiple of 920,991,518,863,638 is 65007389237560.

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.

920 x 991 x 518 x 863 x 638 = 260029556950240

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.

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

991 : 1, 991

518 : 1, 2, 7, 14, 37, 74, 259, 518

863 : 1, 863

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,991,518,863,638, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

991:991

518:2x 7x 37

863:863

638:2x 11x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 260029556950240/(1x4)

LCM = 260029556950240/4

LCM = 65007389237560

Thus, we can understand that the LCM of 920,991,518,863,638 is 65007389237560.
