Given numbers are 121,851,517,440

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

The LCM of 121,851,517,440 is 193585480.

Find LCM of 121,851,517,440 with Prime Factorization

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

11 x 11 x 851 x 47 x 40 = 193585480

Therefore, the lowest common multiple of 121,851,517,440 is 193585480.

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 851 x 517 x 440 = 23423843080

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

851 : 1, 23, 37, 851

517 : 1, 11, 47, 517

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,851,517,440, is 1.

Now, the common factors can be found like this.

121:11x 11

851:23x 37

517:11x 47

440:2x 2x 2x 5x 11

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 23423843080/(1x121)

LCM = 23423843080/121

LCM = 193585480

Thus, we can understand that the LCM of 121,851,517,440 is 193585480.
