Given numbers are 638,863,976,847,968

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

The LCM of 638,863,976,847,968 is 20689120144.

Find LCM of 638,863,976,847,968 with Prime Factorization

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

2 x 2 x 2 x 11 x 11 x 29 x 863 x 122 x 7 x 1 = 20689120144

Therefore, the lowest common multiple of 638,863,976,847,968 is 20689120144.

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.

638 x 863 x 976 x 847 x 968 = 440595502586624

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.

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

863 : 1, 863

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

847 : 1, 7, 11, 77, 121, 847

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,863,976,847,968, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

863:863

976:2x 2x 2x 2x 61

847:7x 11x 11

968:2x 2x 2x 11x 11

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 11x 11x 11 = 21296

Therefore, the value for common factors is 21296.

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 = 440595502586624/(1x21296)

LCM = 440595502586624/21296

LCM = 20689120144

Thus, we can understand that the LCM of 638,863,976,847,968 is 20689120144.
