Calculate the LCM of 391,721,976,623

Given numbers are 391,721,976,623

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

The LCM of 391,721,976,623 is 24487917104.

Find LCM of 391,721,976,623 with Prime Factorization


7 391, 721, 976, 623
391, 103, 976, 89

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

7 x 391 x 103 x 976 x 89 = 24487917104

Therefore, the lowest common multiple of 391,721,976,623 is 24487917104.

LCM Formula to Find Lowest Common Multiple of 391,721,976,623

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.

391 x 721 x 976 x 623 = 171415419728

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.

391 : 1, 17, 23, 391

721 : 1, 7, 103, 721

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

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,721,976,623, is 1.

Now, the common factors can be found like this.

391:17x 23

721:7x 103

976:2x 2x 2x 2x 61

623:7x 89

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

7 = 7

Therefore, the value for common factors is 7.

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 = 171415419728/(1x7)

LCM = 171415419728/7

LCM = 24487917104

Thus, we can understand that the LCM of 391,721,976,623 is 24487917104.
