Given numbers are 121,761,507,338,408

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

The LCM of 121,761,507,338,408 is 6349169112.

Find LCM of 121,761,507,338,408 with Prime Factorization

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

2 x 3 x 13 x 13 x 121 x 761 x 1 x 1 x 68 = 6349169112

Therefore, the lowest common multiple of 121,761,507,338,408 is 6349169112.

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 761 x 507 x 338 x 408 = 6438057479568

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

761 : 1, 761

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

338 : 1, 2, 13, 26, 169, 338

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,761,507,338,408, is 1.

Now, the common factors can be found like this.

121:11x 11

761:761

507:3x 13x 13

338:2x 13x 13

408:2x 2x 2x 3x 17

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

2x 3x 13x 13 = 1014

Therefore, the value for common factors is 1014.

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 = 6438057479568/(1x1014)

LCM = 6438057479568/1014

LCM = 6349169112

Thus, we can understand that the LCM of 121,761,507,338,408 is 6349169112.
