Given numbers are 731,657,818,290

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

The LCM of 731,657,818,290 is 56964468870.

Find LCM of 731,657,818,290 with Prime Factorization

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

2 x 731 x 657 x 409 x 145 = 56964468870

Therefore, the lowest common multiple of 731,657,818,290 is 56964468870.

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.

731 x 657 x 818 x 290 = 113928937740

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.

731 : 1, 17, 43, 731

657 : 1, 3, 9, 73, 219, 657

818 : 1, 2, 409, 818

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,657,818,290, is 1.

Now, the common factors can be found like this.

731:17x 43

657:3x 3x 73

818:2x 409

290:2x 5x 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 = 113928937740/(1x2)

LCM = 113928937740/2

LCM = 56964468870

Thus, we can understand that the LCM of 731,657,818,290 is 56964468870.
