Given numbers are 417,631,354,18

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

The LCM of 417,631,354,18 is 93146958.

Find LCM of 417,631,354,18 with Prime Factorization

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

2 x 3 x 139 x 631 x 59 x 3 = 93146958

Therefore, the lowest common multiple of 417,631,354,18 is 93146958.

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.

417 x 631 x 354 x 18 = 1676645244

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.

417 : 1, 3, 139, 417

631 : 1, 631

354 : 1, 2, 3, 6, 59, 118, 177, 354

18 : 1, 2, 3, 6, 9, 18

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,631,354,18, is 1.

Now, the common factors can be found like this.

417:3x 139

631:631

354:2x 3x 59

18:2x 3x 3

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 1676645244/(1x18)

LCM = 1676645244/18

LCM = 93146958

Thus, we can understand that the LCM of 417,631,354,18 is 93146958.
