Given numbers are 331,117,416,638

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

The LCM of 331,117,416,638 is 395325216.

Find LCM of 331,117,416,638 with Prime Factorization

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

2 x 13 x 331 x 9 x 16 x 319 = 395325216

Therefore, the lowest common multiple of 331,117,416,638 is 395325216.

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.

331 x 117 x 416 x 638 = 10278455616

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.

331 : 1, 331

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

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,117,416,638, is 1.

Now, the common factors can be found like this.

331:331

117:3x 3x 13

416:2x 2x 2x 2x 2x 13

638:2x 11x 29

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 10278455616/(1x26)

LCM = 10278455616/26

LCM = 395325216

Thus, we can understand that the LCM of 331,117,416,638 is 395325216.
