Given numbers are 397,517,478,818

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

The LCM of 397,517,478,818 is 40126589998.

Find LCM of 397,517,478,818 with Prime Factorization

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

2 x 397 x 517 x 239 x 409 = 40126589998

Therefore, the lowest common multiple of 397,517,478,818 is 40126589998.

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.

397 x 517 x 478 x 818 = 80253179996

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.

397 : 1, 397

517 : 1, 11, 47, 517

478 : 1, 2, 239, 478

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,517,478,818, is 1.

Now, the common factors can be found like this.

397:397

517:11x 47

478:2x 239

818:2x 409

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 = 80253179996/(1x2)

LCM = 80253179996/2

LCM = 40126589998

Thus, we can understand that the LCM of 397,517,478,818 is 40126589998.
