Given numbers are 620,720,559,897

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

The LCM of 620,720,559,897 is 286968240.

Find LCM of 620,720,559,897 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 31 x 12 x 43 x 23 = 286968240

Therefore, the lowest common multiple of 620,720,559,897 is 286968240.

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.

620 x 720 x 559 x 897 = 223835227200

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

559 : 1, 13, 43, 559

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,720,559,897, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

720:2x 2x 2x 2x 3x 3x 5

559:13x 43

897:3x 13x 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 3x 5x 13 = 780

Therefore, the value for common factors is 780.

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 = 223835227200/(1x780)

LCM = 223835227200/780

LCM = 286968240

Thus, we can understand that the LCM of 620,720,559,897 is 286968240.
