Given numbers are 731,398,694,356

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

The LCM of 731,398,694,356 is 17970076508.

Find LCM of 731,398,694,356 with Prime Factorization

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

2 x 731 x 199 x 347 x 178 = 17970076508

Therefore, the lowest common multiple of 731,398,694,356 is 17970076508.

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 398 x 694 x 356 = 71880306032

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

398 : 1, 2, 199, 398

694 : 1, 2, 347, 694

356 : 1, 2, 4, 89, 178, 356

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,398,694,356, is 1.

Now, the common factors can be found like this.

731:17x 43

398:2x 199

694:2x 347

356:2x 2x 89

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 71880306032/(1x4)

LCM = 71880306032/4

LCM = 17970076508

Thus, we can understand that the LCM of 731,398,694,356 is 17970076508.
