Given numbers are 812,652,715,540,391

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

The LCM of 812,652,715,540,391 is 999056838780.

Find LCM of 812,652,715,540,391 with Prime Factorization

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

2 x 2 x 5 x 203 x 163 x 143 x 27 x 391 = 999056838780

Therefore, the lowest common multiple of 812,652,715,540,391 is 999056838780.

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.

812 x 652 x 715 x 540 x 391 = 79924547102400

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

652 : 1, 2, 4, 163, 326, 652

715 : 1, 5, 11, 13, 55, 65, 143, 715

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,652,715,540,391, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

652:2x 2x 163

715:5x 11x 13

540:2x 2x 3x 3x 3x 5

391:17x 23

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 5 = 80

Therefore, the value for common factors is 80.

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 = 79924547102400/(1x80)

LCM = 79924547102400/80

LCM = 999056838780

Thus, we can understand that the LCM of 812,652,715,540,391 is 999056838780.
