Given numbers are 630,667,422,685

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

The LCM of 630,667,422,685 is 12147010470.

Find LCM of 630,667,422,685 with Prime Factorization

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

2 x 5 x 63 x 667 x 211 x 137 = 12147010470

Therefore, the lowest common multiple of 630,667,422,685 is 12147010470.

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.

630 x 667 x 422 x 685 = 121470104700

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.

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

667 : 1, 23, 29, 667

422 : 1, 2, 211, 422

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,667,422,685, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

667:23x 29

422:2x 211

685:5x 137

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 121470104700/(1x10)

LCM = 121470104700/10

LCM = 12147010470

Thus, we can understand that the LCM of 630,667,422,685 is 12147010470.
