Given numbers are 116,121,641,120

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

The LCM of 116,121,641,120 is 269912280.

Find LCM of 116,121,641,120 with Prime Factorization

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

2 x 2 x 29 x 121 x 641 x 30 = 269912280

Therefore, the lowest common multiple of 116,121,641,120 is 269912280.

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.

116 x 121 x 641 x 120 = 1079649120

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.

116 : 1, 2, 4, 29, 58, 116

121 : 1, 11, 121

641 : 1, 641

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 116,121,641,120, is 1.

Now, the common factors can be found like this.

116:2x 2x 29

121:11x 11

641:641

120:2x 2x 2x 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 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 = 1079649120/(1x4)

LCM = 1079649120/4

LCM = 269912280

Thus, we can understand that the LCM of 116,121,641,120 is 269912280.
