Given numbers are 121,716,565,790

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

The LCM of 121,716,565,790 is 3866997860.

Find LCM of 121,716,565,790 with Prime Factorization

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

2 x 5 x 121 x 358 x 113 x 79 = 3866997860

Therefore, the lowest common multiple of 121,716,565,790 is 3866997860.

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 716 x 565 x 790 = 38669978600

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

716 : 1, 2, 4, 179, 358, 716

565 : 1, 5, 113, 565

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,716,565,790, is 1.

Now, the common factors can be found like this.

121:11x 11

716:2x 2x 179

565:5x 113

790:2x 5x 79

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 38669978600/(1x10)

LCM = 38669978600/10

LCM = 3866997860

Thus, we can understand that the LCM of 121,716,565,790 is 3866997860.
