Given numbers are 817,422,630,427

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

The LCM of 817,422,630,427 is 6624832410.

Find LCM of 817,422,630,427 with Prime Factorization

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

2 x 7 x 817 x 211 x 45 x 61 = 6624832410

Therefore, the lowest common multiple of 817,422,630,427 is 6624832410.

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.

817 x 422 x 630 x 427 = 92747653740

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.

817 : 1, 19, 43, 817

422 : 1, 2, 211, 422

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

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,422,630,427, is 1.

Now, the common factors can be found like this.

817:19x 43

422:2x 211

630:2x 3x 3x 5x 7

427:7x 61

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 92747653740/(1x14)

LCM = 92747653740/14

LCM = 6624832410

Thus, we can understand that the LCM of 817,422,630,427 is 6624832410.
