Given numbers are 117,722,644,194,421

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

The LCM of 117,722,644,194,421 is 1110792045636.

Find LCM of 117,722,644,194,421 with Prime Factorization

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

2 x 117 x 361 x 322 x 97 x 421 = 1110792045636

Therefore, the lowest common multiple of 117,722,644,194,421 is 1110792045636.

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 722 x 644 x 194 x 421 = 4443168182544

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

722 : 1, 2, 19, 38, 361, 722

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

194 : 1, 2, 97, 194

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,722,644,194,421, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

722:2x 19x 19

644:2x 2x 7x 23

194:2x 97

421:421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4443168182544/(1x4)

LCM = 4443168182544/4

LCM = 1110792045636

Thus, we can understand that the LCM of 117,722,644,194,421 is 1110792045636.
