Given numbers are 390,671,685,278

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

The LCM of 390,671,685,278 is 4983362670.

Find LCM of 390,671,685,278 with Prime Factorization

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

2 x 5 x 39 x 671 x 137 x 139 = 4983362670

Therefore, the lowest common multiple of 390,671,685,278 is 4983362670.

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.

390 x 671 x 685 x 278 = 49833626700

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

671 : 1, 11, 61, 671

685 : 1, 5, 137, 685

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,671,685,278, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

671:11x 61

685:5x 137

278:2x 139

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 49833626700/(1x10)

LCM = 49833626700/10

LCM = 4983362670

Thus, we can understand that the LCM of 390,671,685,278 is 4983362670.
