Given numbers are 393,721,418,116

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

The LCM of 393,721,418,116 is 6869610132.

Find LCM of 393,721,418,116 with Prime Factorization

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

2 x 393 x 721 x 209 x 58 = 6869610132

Therefore, the lowest common multiple of 393,721,418,116 is 6869610132.

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.

393 x 721 x 418 x 116 = 13739220264

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.

393 : 1, 3, 131, 393

721 : 1, 7, 103, 721

418 : 1, 2, 11, 19, 22, 38, 209, 418

116 : 1, 2, 4, 29, 58, 116

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,721,418,116, is 1.

Now, the common factors can be found like this.

393:3x 131

721:7x 103

418:2x 11x 19

116:2x 2x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 13739220264/(1x2)

LCM = 13739220264/2

LCM = 6869610132

Thus, we can understand that the LCM of 393,721,418,116 is 6869610132.
