Given numbers are 121,447,120,368

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

The LCM of 121,447,120,368 is 99520080.

Find LCM of 121,447,120,368 with Prime Factorization

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

2 x 2 x 2 x 3 x 121 x 149 x 5 x 46 = 99520080

Therefore, the lowest common multiple of 121,447,120,368 is 99520080.

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 447 x 120 x 368 = 2388481920

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

447 : 1, 3, 149, 447

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,447,120,368, is 1.

Now, the common factors can be found like this.

121:11x 11

447:3x 149

120:2x 2x 2x 3x 5

368:2x 2x 2x 2x 23

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 3 = 24

Therefore, the value for common factors is 24.

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 = 2388481920/(1x24)

LCM = 2388481920/24

LCM = 99520080

Thus, we can understand that the LCM of 121,447,120,368 is 99520080.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 821, 667, 301, 259
