Given numbers are 991,750,638,464

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

The LCM of 991,750,638,464 is 1896774000.

Find LCM of 991,750,638,464 with Prime Factorization

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

2 x 29 x 991 x 375 x 11 x 8 = 1896774000

Therefore, the lowest common multiple of 991,750,638,464 is 1896774000.

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.

991 x 750 x 638 x 464 = 220025784000

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.

991 : 1, 991

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,750,638,464, is 1.

Now, the common factors can be found like this.

991:991

750:2x 3x 5x 5x 5

638:2x 11x 29

464:2x 2x 2x 2x 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 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 = 220025784000/(1x116)

LCM = 220025784000/116

LCM = 1896774000

Thus, we can understand that the LCM of 991,750,638,464 is 1896774000.
