Given numbers are 862,551,643,702,631

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

The LCM of 862,551,643,702,631 is 67640422758246.

Find LCM of 862,551,643,702,631 with Prime Factorization

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

2 x 431 x 551 x 643 x 351 x 631 = 67640422758246

Therefore, the lowest common multiple of 862,551,643,702,631 is 67640422758246.

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.

862 x 551 x 643 x 702 x 631 = 135280845516492

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.

862 : 1, 2, 431, 862

551 : 1, 19, 29, 551

643 : 1, 643

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

631 : 1, 631

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,551,643,702,631, is 1.

Now, the common factors can be found like this.

862:2x 431

551:19x 29

643:643

702:2x 3x 3x 3x 13

631:631

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

2 = 2

Therefore, the value for common factors is 2.

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 = 135280845516492/(1x2)

LCM = 135280845516492/2

LCM = 67640422758246

Thus, we can understand that the LCM of 862,551,643,702,631 is 67640422758246.
