Given numbers are 520,503,655,420,924

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

The LCM of 520,503,655,420,924 is 7915067160.

Find LCM of 520,503,655,420,924 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 26 x 503 x 131 x 1 x 11 = 7915067160

Therefore, the lowest common multiple of 520,503,655,420,924 is 7915067160.

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 503 x 655 x 420 x 924 = 66486564144000

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

503 : 1, 503

655 : 1, 5, 131, 655

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,503,655,420,924, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

503:503

655:5x 131

420:2x 2x 3x 5x 7

924:2x 2x 3x 7x 11

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 2x 3x 5x 5x 7 = 8400

Therefore, the value for common factors is 8400.

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 = 66486564144000/(1x8400)

LCM = 66486564144000/8400

LCM = 7915067160

Thus, we can understand that the LCM of 520,503,655,420,924 is 7915067160.
