Given numbers are 721,908,662,190

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

The LCM of 721,908,662,190 is 20586035260.

Find LCM of 721,908,662,190 with Prime Factorization

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

2 x 721 x 454 x 331 x 95 = 20586035260

Therefore, the lowest common multiple of 721,908,662,190 is 20586035260.

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.

721 x 908 x 662 x 190 = 82344141040

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.

721 : 1, 7, 103, 721

908 : 1, 2, 4, 227, 454, 908

662 : 1, 2, 331, 662

190 : 1, 2, 5, 10, 19, 38, 95, 190

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,908,662,190, is 1.

Now, the common factors can be found like this.

721:7x 103

908:2x 2x 227

662:2x 331

190:2x 5x 19

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 = 82344141040/(1x4)

LCM = 82344141040/4

LCM = 20586035260

Thus, we can understand that the LCM of 721,908,662,190 is 20586035260.
