Given numbers are 520,172,826,630

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

The LCM of 520,172,826,630 is 83112120.

Find LCM of 520,172,826,630 with Prime Factorization

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

2 x 2 x 5 x 7 x 26 x 43 x 59 x 9 = 83112120

Therefore, the lowest common multiple of 520,172,826,630 is 83112120.

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.

520 x 172 x 826 x 630 = 46542787200

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

172 : 1, 2, 4, 43, 86, 172

826 : 1, 2, 7, 14, 59, 118, 413, 826

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,172,826,630, is 2.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

172:2x 2x 43

826:2x 7x 59

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 2x 2x 5x 7 = 280

Therefore, the value for common factors is 280.

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 = 46542787200/(2x280)

LCM = 46542787200/560

LCM = 83112120

Thus, we can understand that the LCM of 520,172,826,630 is 83112120.
