Given numbers are 920,546,457,620

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

The LCM of 920,546,457,620 is 3558183720.

Find LCM of 920,546,457,620 with Prime Factorization

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

2 x 2 x 5 x 46 x 273 x 457 x 31 = 3558183720

Therefore, the lowest common multiple of 920,546,457,620 is 3558183720.

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 546 x 457 x 620 = 142327348800

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

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

457 : 1, 457

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,546,457,620, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

546:2x 3x 7x 13

457:457

620:2x 2x 5x 31

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 = 142327348800/(1x40)

LCM = 142327348800/40

LCM = 3558183720

Thus, we can understand that the LCM of 920,546,457,620 is 3558183720.
