Given numbers are 120,221,869,716

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

The LCM of 120,221,869,716 is 4125212520.

Find LCM of 120,221,869,716 with Prime Factorization

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

2 x 2 x 30 x 221 x 869 x 179 = 4125212520

Therefore, the lowest common multiple of 120,221,869,716 is 4125212520.

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.

120 x 221 x 869 x 716 = 16500850080

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.

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

221 : 1, 13, 17, 221

869 : 1, 11, 79, 869

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,221,869,716, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

221:13x 17

869:11x 79

716:2x 2x 179

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 16500850080/(1x4)

LCM = 16500850080/4

LCM = 4125212520

Thus, we can understand that the LCM of 120,221,869,716 is 4125212520.
