Given numbers are 857,691,689,702

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

The LCM of 857,691,689,702 is 22032909522.

Find LCM of 857,691,689,702 with Prime Factorization

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

13 x 857 x 691 x 53 x 54 = 22032909522

Therefore, the lowest common multiple of 857,691,689,702 is 22032909522.

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 691 x 689 x 702 = 286427823786

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

691 : 1, 691

689 : 1, 13, 53, 689

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,691,689,702, is 1.

Now, the common factors can be found like this.

857:857

691:691

689:13x 53

702:2x 3x 3x 3x 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 = 286427823786/(1x13)

LCM = 286427823786/13

LCM = 22032909522

Thus, we can understand that the LCM of 857,691,689,702 is 22032909522.
