Given numbers are 647,951,444,630

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

The LCM of 647,951,444,630 is 9561715380.

Find LCM of 647,951,444,630 with Prime Factorization

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

2 x 3 x 647 x 317 x 74 x 105 = 9561715380

Therefore, the lowest common multiple of 647,951,444,630 is 9561715380.

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.

647 x 951 x 444 x 630 = 172110876840

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.

647 : 1, 647

951 : 1, 3, 317, 951

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,951,444,630, is 1.

Now, the common factors can be found like this.

647:647

951:3x 317

444:2x 2x 3x 37

630:2x 3x 3x 5x 7

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 172110876840/(1x18)

LCM = 172110876840/18

LCM = 9561715380

Thus, we can understand that the LCM of 647,951,444,630 is 9561715380.
