Given numbers are 976,491,221,380,747

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

The LCM of 976,491,221,380,747 is 7515671520240.

Find LCM of 976,491,221,380,747 with Prime Factorization

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

2 x 2 x 244 x 491 x 221 x 95 x 747 = 7515671520240

Therefore, the lowest common multiple of 976,491,221,380,747 is 7515671520240.

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.

976 x 491 x 221 x 380 x 747 = 30062686080960

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.

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

491 : 1, 491

221 : 1, 13, 17, 221

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,491,221,380,747, is 1.

Now, the common factors can be found like this.

976:2x 2x 2x 2x 61

491:491

221:13x 17

380:2x 2x 5x 19

747:3x 3x 83

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 = 30062686080960/(1x4)

LCM = 30062686080960/4

LCM = 7515671520240

Thus, we can understand that the LCM of 976,491,221,380,747 is 7515671520240.
