Given numbers are 399,646,893,922

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

The LCM of 399,646,893,922 is 293934522.

Find LCM of 399,646,893,922 with Prime Factorization

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

2 x 19 x 21 x 17 x 47 x 461 = 293934522

Therefore, the lowest common multiple of 399,646,893,922 is 293934522.

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.

399 x 646 x 893 x 922 = 212220724884

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

646 : 1, 2, 17, 19, 34, 38, 323, 646

893 : 1, 19, 47, 893

922 : 1, 2, 461, 922

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,646,893,922, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

646:2x 17x 19

893:19x 47

922:2x 461

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

2x 19x 19 = 722

Therefore, the value for common factors is 722.

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 = 212220724884/(1x722)

LCM = 212220724884/722

LCM = 293934522

Thus, we can understand that the LCM of 399,646,893,922 is 293934522.
