Given numbers are 194,731,164,420

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

The LCM of 194,731,164,420 is 1221018540.

Find LCM of 194,731,164,420 with Prime Factorization

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

2 x 2 x 97 x 731 x 41 x 105 = 1221018540

Therefore, the lowest common multiple of 194,731,164,420 is 1221018540.

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.

194 x 731 x 164 x 420 = 9768148320

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.

194 : 1, 2, 97, 194

731 : 1, 17, 43, 731

164 : 1, 2, 4, 41, 82, 164

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,731,164,420, is 1.

Now, the common factors can be found like this.

194:2x 97

731:17x 43

164:2x 2x 41

420:2x 2x 3x 5x 7

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 = 9768148320/(1x8)

LCM = 9768148320/8

LCM = 1221018540

Thus, we can understand that the LCM of 194,731,164,420 is 1221018540.
