Given numbers are 640,839,539,283,198

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

The LCM of 640,839,539,283,198 is 737156407680.

Find LCM of 640,839,539,283,198 with Prime Factorization

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

2 x 11 x 320 x 839 x 49 x 283 x 9 = 737156407680

Therefore, the lowest common multiple of 640,839,539,283,198 is 737156407680.

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.

640 x 839 x 539 x 283 x 198 = 16217440968960

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

839 : 1, 839

539 : 1, 7, 11, 49, 77, 539

283 : 1, 283

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,839,539,283,198, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

839:839

539:7x 7x 11

283:283

198:2x 3x 3x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 16217440968960/(1x22)

LCM = 16217440968960/22

LCM = 737156407680

Thus, we can understand that the LCM of 640,839,539,283,198 is 737156407680.
