Given numbers are 117,921,462,857

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

The LCM of 117,921,462,857 is 4740517782.

Find LCM of 117,921,462,857 with Prime Factorization

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

3 x 39 x 307 x 154 x 857 = 4740517782

Therefore, the lowest common multiple of 117,921,462,857 is 4740517782.

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.

117 x 921 x 462 x 857 = 42664660038

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.

117 : 1, 3, 9, 13, 39, 117

921 : 1, 3, 307, 921

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,921,462,857, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

921:3x 307

462:2x 3x 7x 11

857:857

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 42664660038/(1x9)

LCM = 42664660038/9

LCM = 4740517782

Thus, we can understand that the LCM of 117,921,462,857 is 4740517782.
