Given numbers are 121,638,190,779,360

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

The LCM of 121,638,190,779,360 is 984063960.

Find LCM of 121,638,190,779,360 with Prime Factorization

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

2 x 5 x 11 x 19 x 11 x 29 x 1 x 41 x 36 = 984063960

Therefore, the lowest common multiple of 121,638,190,779,360 is 984063960.

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 638 x 190 x 779 x 360 = 4113387352800

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

190 : 1, 2, 5, 10, 19, 38, 95, 190

779 : 1, 19, 41, 779

360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,638,190,779,360, is 1.

Now, the common factors can be found like this.

121:11x 11

638:2x 11x 29

190:2x 5x 19

779:19x 41

360:2x 2x 2x 3x 3x 5

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

2x 2x 5x 11x 19 = 4180

Therefore, the value for common factors is 4180.

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 = 4113387352800/(1x4180)

LCM = 4113387352800/4180

LCM = 984063960

Thus, we can understand that the LCM of 121,638,190,779,360 is 984063960.
