Calculate the LCM of 121,550,891,507

Given numbers are 121,550,891,507

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

The LCM of 121,550,891,507 is 82818450.

Find LCM of 121,550,891,507 with Prime Factorization


3 121, 550, 891, 507
11 121, 550, 297, 169
11, 50, 27, 169

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

3 x 11 x 11 x 50 x 27 x 169 = 82818450

Therefore, the lowest common multiple of 121,550,891,507 is 82818450.

LCM Formula to Find Lowest Common Multiple of 121,550,891,507

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.

121 x 550 x 891 x 507 = 30063097350

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.

121 : 1, 11, 121

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

507 : 1, 3, 13, 39, 169, 507

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,550,891,507, is 1.

Now, the common factors can be found like this.

121:11x 11

550:2x 5x 5x 11

891:3x 3x 3x 3x 11

507:3x 13x 13

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

3x 11x 11 = 363

Therefore, the value for common factors is 363.

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 = 30063097350/(1x363)

LCM = 30063097350/363

LCM = 82818450

Thus, we can understand that the LCM of 121,550,891,507 is 82818450.
