Given numbers are 920,221,546,858,764

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

The LCM of 920,221,546,858,764 is 8970681720.

Find LCM of 920,221,546,858,764 with Prime Factorization

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

2 x 2 x 3 x 13 x 230 x 17 x 7 x 11 x 191 = 8970681720

Therefore, the lowest common multiple of 920,221,546,858,764 is 8970681720.

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.

920 x 221 x 546 x 858 x 764 = 72770170112640

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

221 : 1, 13, 17, 221

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

764 : 1, 2, 4, 191, 382, 764

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,221,546,858,764, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

221:13x 17

546:2x 3x 7x 13

858:2x 3x 11x 13

764:2x 2x 191

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 3x 13x 13 = 8112

Therefore, the value for common factors is 8112.

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 = 72770170112640/(1x8112)

LCM = 72770170112640/8112

LCM = 8970681720

Thus, we can understand that the LCM of 920,221,546,858,764 is 8970681720.
