Given numbers are 121,291,992,516,540

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

The LCM of 121,291,992,516,540 is 67588218720.

Find LCM of 121,291,992,516,540 with Prime Factorization

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

2 x 2 x 3 x 121 x 97 x 248 x 43 x 45 = 67588218720

Therefore, the lowest common multiple of 121,291,992,516,540 is 67588218720.

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 291 x 992 x 516 x 540 = 9732703495680

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

291 : 1, 3, 97, 291

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,291,992,516,540, is 1.

Now, the common factors can be found like this.

121:11x 11

291:3x 97

992:2x 2x 2x 2x 2x 31

516:2x 2x 3x 43

540:2x 2x 3x 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 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 9732703495680/(1x144)

LCM = 9732703495680/144

LCM = 67588218720

Thus, we can understand that the LCM of 121,291,992,516,540 is 67588218720.
