Given numbers are 620,377,772,380,408

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

The LCM of 620,377,772,380,408 is 87426707160.

Find LCM of 620,377,772,380,408 with Prime Factorization

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

2 x 2 x 5 x 31 x 377 x 193 x 19 x 102 = 87426707160

Therefore, the lowest common multiple of 620,377,772,380,408 is 87426707160.

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.

620 x 377 x 772 x 380 x 408 = 27976546291200

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.

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

377 : 1, 13, 29, 377

772 : 1, 2, 4, 193, 386, 772

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,377,772,380,408, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

377:13x 29

772:2x 2x 193

380:2x 2x 5x 19

408:2x 2x 2x 3x 17

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 2x 5 = 320

Therefore, the value for common factors is 320.

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 = 27976546291200/(1x320)

LCM = 27976546291200/320

LCM = 87426707160

Thus, we can understand that the LCM of 620,377,772,380,408 is 87426707160.
