Given numbers are 812,946,720,858,643

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

The LCM of 812,946,720,858,643 is 577888431120.

Find LCM of 812,946,720,858,643 with Prime Factorization

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

2 x 2 x 3 x 11 x 203 x 43 x 60 x 13 x 643 = 577888431120

Therefore, the lowest common multiple of 812,946,720,858,643 is 577888431120.

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.

812 x 946 x 720 x 858 x 643 = 305125091631360

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

946 : 1, 2, 11, 22, 43, 86, 473, 946

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

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

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,946,720,858,643, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

946:2x 11x 43

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

858:2x 3x 11x 13

643:643

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 11 = 528

Therefore, the value for common factors is 528.

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 = 305125091631360/(1x528)

LCM = 305125091631360/528

LCM = 577888431120

Thus, we can understand that the LCM of 812,946,720,858,643 is 577888431120.
