Given numbers are 830,457,208,120,620

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

The LCM of 830,457,208,120,620 is 3668686320.

Find LCM of 830,457,208,120,620 with Prime Factorization

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

2 x 2 x 2 x 5 x 83 x 457 x 26 x 3 x 31 = 3668686320

Therefore, the lowest common multiple of 830,457,208,120,620 is 3668686320.

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.

830 x 457 x 208 x 120 x 620 = 5869898112000

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

457 : 1, 457

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

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 830,457,208,120,620, is 1.

Now, the common factors can be found like this.

830:2x 5x 83

457:457

208:2x 2x 2x 2x 13

120:2x 2x 2x 3x 5

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 2x 2x 2x 5x 5 = 1600

Therefore, the value for common factors is 1600.

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 = 5869898112000/(1x1600)

LCM = 5869898112000/1600

LCM = 3668686320

Thus, we can understand that the LCM of 830,457,208,120,620 is 3668686320.
