Given numbers are 318,731,393,91

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

The LCM of 318,731,393,91 is 2771131818.

Find LCM of 318,731,393,91 with Prime Factorization

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

3 x 106 x 731 x 131 x 91 = 2771131818

Therefore, the lowest common multiple of 318,731,393,91 is 2771131818.

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.

318 x 731 x 393 x 91 = 8313395454

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.

318 : 1, 2, 3, 6, 53, 106, 159, 318

731 : 1, 17, 43, 731

393 : 1, 3, 131, 393

91 : 1, 7, 13, 91

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,731,393,91, is 1.

Now, the common factors can be found like this.

318:2x 3x 53

731:17x 43

393:3x 131

91:7x 13

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

3 = 3

Therefore, the value for common factors is 3.

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 = 8313395454/(1x3)

LCM = 8313395454/3

LCM = 2771131818

Thus, we can understand that the LCM of 318,731,393,91 is 2771131818.
