Given numbers are 857,557,749,208,715

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

The LCM of 857,557,749,208,715 is 4090193547440.

Find LCM of 857,557,749,208,715 with Prime Factorization

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

13 x 857 x 557 x 749 x 16 x 55 = 4090193547440

Therefore, the lowest common multiple of 857,557,749,208,715 is 4090193547440.

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.

857 x 557 x 749 x 208 x 715 = 53172516116720

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.

857 : 1, 857

557 : 1, 557

749 : 1, 7, 107, 749

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,557,749,208,715, is 1.

Now, the common factors can be found like this.

857:857

557:557

749:7x 107

208:2x 2x 2x 2x 13

715:5x 11x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 53172516116720/(1x13)

LCM = 53172516116720/13

LCM = 4090193547440

Thus, we can understand that the LCM of 857,557,749,208,715 is 4090193547440.
