Given numbers are 680,994,442,612,889

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

The LCM of 680,994,442,612,889 is 5021747640.

Find LCM of 680,994,442,612,889 with Prime Factorization

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

2 x 2 x 7 x 17 x 10 x 71 x 13 x 9 x 127 = 5021747640

Therefore, the lowest common multiple of 680,994,442,612,889 is 5021747640.

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.

680 x 994 x 442 x 612 x 889 = 162543927611520

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

994 : 1, 2, 7, 14, 71, 142, 497, 994

442 : 1, 2, 13, 17, 26, 34, 221, 442

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,994,442,612,889, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

994:2x 7x 71

442:2x 13x 17

612:2x 2x 3x 3x 17

889:7x 127

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 7x 17x 17 = 32368

Therefore, the value for common factors is 32368.

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 = 162543927611520/(1x32368)

LCM = 162543927611520/32368

LCM = 5021747640

Thus, we can understand that the LCM of 680,994,442,612,889 is 5021747640.
