Given numbers are 672,864,121,861,577

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

The LCM of 672,864,121,861,577 is 17312381856.

Find LCM of 672,864,121,861,577 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 3 x 7 x 1 x 9 x 121 x 41 x 577 = 17312381856

Therefore, the lowest common multiple of 672,864,121,861,577 is 17312381856.

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.

672 x 864 x 121 x 861 x 577 = 34901761821696

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

121 : 1, 11, 121

861 : 1, 3, 7, 21, 41, 123, 287, 861

577 : 1, 577

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,864,121,861,577, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

864:2x 2x 2x 2x 2x 3x 3x 3

121:11x 11

861:3x 7x 41

577:577

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 3x 3x 7 = 2016

Therefore, the value for common factors is 2016.

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 = 34901761821696/(1x2016)

LCM = 34901761821696/2016

LCM = 17312381856

Thus, we can understand that the LCM of 672,864,121,861,577 is 17312381856.
