Given numbers are 645,698,572,104,796

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

The LCM of 645,698,572,104,796 is 51246503880.

Find LCM of 645,698,572,104,796 with Prime Factorization

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

2 x 2 x 13 x 645 x 349 x 11 x 2 x 199 = 51246503880

Therefore, the lowest common multiple of 645,698,572,104,796 is 51246503880.

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.

645 x 698 x 572 x 104 x 796 = 21318545614080

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

698 : 1, 2, 349, 698

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

104 : 1, 2, 4, 8, 13, 26, 52, 104

796 : 1, 2, 4, 199, 398, 796

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,698,572,104,796, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

698:2x 349

572:2x 2x 11x 13

104:2x 2x 2x 13

796:2x 2x 199

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 2x 13 = 416

Therefore, the value for common factors is 416.

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 = 21318545614080/(1x416)

LCM = 21318545614080/416

LCM = 51246503880

Thus, we can understand that the LCM of 645,698,572,104,796 is 51246503880.
