Given numbers are 787,646,299,766,720

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

The LCM of 787,646,299,766,720 is 20959441860240.

Find LCM of 787,646,299,766,720 with Prime Factorization

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

2 x 787 x 323 x 299 x 383 x 360 = 20959441860240

Therefore, the lowest common multiple of 787,646,299,766,720 is 20959441860240.

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.

787 x 646 x 299 x 766 x 720 = 83837767440960

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.

787 : 1, 787

646 : 1, 2, 17, 19, 34, 38, 323, 646

299 : 1, 13, 23, 299

766 : 1, 2, 383, 766

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,646,299,766,720, is 1.

Now, the common factors can be found like this.

787:787

646:2x 17x 19

299:13x 23

766:2x 383

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

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 83837767440960/(1x4)

LCM = 83837767440960/4

LCM = 20959441860240

Thus, we can understand that the LCM of 787,646,299,766,720 is 20959441860240.
