Given numbers are 668,272,741,620

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

The LCM of 668,272,741,620 is 5217173520.

Find LCM of 668,272,741,620 with Prime Factorization

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

2 x 2 x 167 x 68 x 741 x 155 = 5217173520

Therefore, the lowest common multiple of 668,272,741,620 is 5217173520.

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.

668 x 272 x 741 x 620 = 83474776320

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.

668 : 1, 2, 4, 167, 334, 668

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

741 : 1, 3, 13, 19, 39, 57, 247, 741

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 668,272,741,620, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

272:2x 2x 2x 2x 17

741:3x 13x 19

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 2 = 16

Therefore, the value for common factors is 16.

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 = 83474776320/(1x16)

LCM = 83474776320/16

LCM = 5217173520

Thus, we can understand that the LCM of 668,272,741,620 is 5217173520.
