Given numbers are 278,694,454,852,685

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

The LCM of 278,694,454,852,685 is 6389991765420.

Find LCM of 278,694,454,852,685 with Prime Factorization

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

2 x 139 x 347 x 227 x 426 x 685 = 6389991765420

Therefore, the lowest common multiple of 278,694,454,852,685 is 6389991765420.

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.

278 x 694 x 454 x 852 x 685 = 51119934123360

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.

278 : 1, 2, 139, 278

694 : 1, 2, 347, 694

454 : 1, 2, 227, 454

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,694,454,852,685, is 1.

Now, the common factors can be found like this.

278:2x 139

694:2x 347

454:2x 227

852:2x 2x 3x 71

685:5x 137

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 2 = 8

Therefore, the value for common factors is 8.

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 = 51119934123360/(1x8)

LCM = 51119934123360/8

LCM = 6389991765420

Thus, we can understand that the LCM of 278,694,454,852,685 is 6389991765420.
