Given numbers are 121,868,490,195,406

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

The LCM of 121,868,490,195,406 is 4157533380.

Find LCM of 121,868,490,195,406 with Prime Factorization

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

2 x 5 x 7 x 121 x 62 x 7 x 39 x 29 = 4157533380

Therefore, the lowest common multiple of 121,868,490,195,406 is 4157533380.

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 868 x 490 x 195 x 406 = 4074382712400

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

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

195 : 1, 3, 5, 13, 15, 39, 65, 195

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,868,490,195,406, is 1.

Now, the common factors can be found like this.

121:11x 11

868:2x 2x 7x 31

490:2x 5x 7x 7

195:3x 5x 13

406:2x 7x 29

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 7x 7 = 980

Therefore, the value for common factors is 980.

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 = 4074382712400/(1x980)

LCM = 4074382712400/980

LCM = 4157533380

Thus, we can understand that the LCM of 121,868,490,195,406 is 4157533380.
