Given numbers are 520,953,638,215,428

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

The LCM of 520,953,638,215,428 is 727342827640.

Find LCM of 520,953,638,215,428 with Prime Factorization

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

2 x 2 x 5 x 26 x 953 x 319 x 43 x 107 = 727342827640

Therefore, the lowest common multiple of 520,953,638,215,428 is 727342827640.

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 953 x 638 x 215 x 428 = 29093713105600

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

953 : 1, 953

638 : 1, 2, 11, 22, 29, 58, 319, 638

215 : 1, 5, 43, 215

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,953,638,215,428, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

953:953

638:2x 11x 29

215:5x 43

428:2x 2x 107

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 5 = 40

Therefore, the value for common factors is 40.

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 = 29093713105600/(1x40)

LCM = 29093713105600/40

LCM = 727342827640

Thus, we can understand that the LCM of 520,953,638,215,428 is 727342827640.
