Given numbers are 660,917,715,702,406

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

The LCM of 660,917,715,702,406 is 2053511460.

Find LCM of 660,917,715,702,406 with Prime Factorization

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

2 x 3 x 5 x 7 x 11 x 13 x 2 x 131 x 1 x 9 x 29 = 2053511460

Therefore, the lowest common multiple of 660,917,715,702,406 is 2053511460.

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.

660 x 917 x 715 x 702 x 406 = 123333898287600

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

917 : 1, 7, 131, 917

715 : 1, 5, 11, 13, 55, 65, 143, 715

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,917,715,702,406, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

917:7x 131

715:5x 11x 13

702:2x 3x 3x 3x 13

406:2x 7x 29

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 3x 5x 7x 11x 13 = 60060

Therefore, the value for common factors is 60060.

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 = 123333898287600/(1x60060)

LCM = 123333898287600/60060

LCM = 2053511460

Thus, we can understand that the LCM of 660,917,715,702,406 is 2053511460.
