Given numbers are 660,641,121,194

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

The LCM of 660,641,121,194 is 451405020.

Find LCM of 660,641,121,194 with Prime Factorization

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

2 x 11 x 30 x 641 x 11 x 97 = 451405020

Therefore, the lowest common multiple of 660,641,121,194 is 451405020.

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.

660 x 641 x 121 x 194 = 9930910440

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

641 : 1, 641

121 : 1, 11, 121

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,641,121,194, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

641:641

121:11x 11

194:2x 97

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 9930910440/(1x22)

LCM = 9930910440/22

LCM = 451405020

Thus, we can understand that the LCM of 660,641,121,194 is 451405020.
