Given numbers are 121,630,680,349,284

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

The LCM of 121,630,680,349,284 is 128445415560.

Find LCM of 121,630,680,349,284 with Prime Factorization

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

2 x 2 x 5 x 121 x 63 x 34 x 349 x 71 = 128445415560

Therefore, the lowest common multiple of 121,630,680,349,284 is 128445415560.

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 630 x 680 x 349 x 284 = 5137816622400

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

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

349 : 1, 349

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,630,680,349,284, is 1.

Now, the common factors can be found like this.

121:11x 11

630:2x 3x 3x 5x 7

680:2x 2x 2x 5x 17

349:349

284:2x 2x 71

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 5137816622400/(1x40)

LCM = 5137816622400/40

LCM = 128445415560

Thus, we can understand that the LCM of 121,630,680,349,284 is 128445415560.
