Given numbers are 2,638,464,817

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

The LCM of 2,638,464,817 is 4169968.

Find LCM of 2,638,464,817 with Prime Factorization

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

2 x 29 x 1 x 11 x 8 x 817 = 4169968

Therefore, the lowest common multiple of 2,638,464,817 is 4169968.

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.

2 x 638 x 464 x 817 = 483716288

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.

2 : 1, 2

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

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,638,464,817, is 1.

Now, the common factors can be found like this.

2:2

638:2x 11x 29

464:2x 2x 2x 2x 29

817:19x 43

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 29 = 116

Therefore, the value for common factors is 116.

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 = 483716288/(1x116)

LCM = 483716288/116

LCM = 4169968

Thus, we can understand that the LCM of 2,638,464,817 is 4169968.
