Given numbers are 671,990,319,460

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

The LCM of 671,990,319,460 is 80560260.

Find LCM of 671,990,319,460 with Prime Factorization

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

2 x 5 x 11 x 61 x 9 x 29 x 46 = 80560260

Therefore, the lowest common multiple of 671,990,319,460 is 80560260.

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.

671 x 990 x 319 x 460 = 97477914600

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.

671 : 1, 11, 61, 671

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

319 : 1, 11, 29, 319

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,990,319,460, is 1.

Now, the common factors can be found like this.

671:11x 61

990:2x 3x 3x 5x 11

319:11x 29

460:2x 2x 5x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 11x 11 = 1210

Therefore, the value for common factors is 1210.

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 = 97477914600/(1x1210)

LCM = 97477914600/1210

LCM = 80560260

Thus, we can understand that the LCM of 671,990,319,460 is 80560260.
