Given numbers are 392,982,515,566,643

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

The LCM of 392,982,515,566,643 is 18037327744520.

Find LCM of 392,982,515,566,643 with Prime Factorization

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

2 x 196 x 491 x 515 x 283 x 643 = 18037327744520

Therefore, the lowest common multiple of 392,982,515,566,643 is 18037327744520.

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.

392 x 982 x 515 x 566 x 643 = 72149310978080

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

982 : 1, 2, 491, 982

515 : 1, 5, 103, 515

566 : 1, 2, 283, 566

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,982,515,566,643, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

982:2x 491

515:5x 103

566:2x 283

643:643

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 = 72149310978080/(1x4)

LCM = 72149310978080/4

LCM = 18037327744520

Thus, we can understand that the LCM of 392,982,515,566,643 is 18037327744520.
