Given numbers are 986,420,857,920

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

The LCM of 986,420,857,920 is 8162719320.

Find LCM of 986,420,857,920 with Prime Factorization

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

2 x 2 x 5 x 493 x 21 x 857 x 46 = 8162719320

Therefore, the lowest common multiple of 986,420,857,920 is 8162719320.

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.

986 x 420 x 857 x 920 = 326508772800

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.

986 : 1, 2, 17, 29, 34, 58, 493, 986

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

857 : 1, 857

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,420,857,920, is 1.

Now, the common factors can be found like this.

986:2x 17x 29

420:2x 2x 3x 5x 7

857:857

920:2x 2x 2x 5x 23

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 5 = 40

Therefore, the value for common factors is 40.

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 = 326508772800/(1x40)

LCM = 326508772800/40

LCM = 8162719320

Thus, we can understand that the LCM of 986,420,857,920 is 8162719320.
