Given numbers are 722,355,985,80

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

The LCM of 722,355,985,80 is 403944560.

Find LCM of 722,355,985,80 with Prime Factorization

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

2 x 5 x 361 x 71 x 197 x 8 = 403944560

Therefore, the lowest common multiple of 722,355,985,80 is 403944560.

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.

722 x 355 x 985 x 80 = 20197228000

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.

722 : 1, 2, 19, 38, 361, 722

355 : 1, 5, 71, 355

985 : 1, 5, 197, 985

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,355,985,80, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

355:5x 71

985:5x 197

80:2x 2x 2x 2x 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 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 20197228000/(1x50)

LCM = 20197228000/50

LCM = 403944560

Thus, we can understand that the LCM of 722,355,985,80 is 403944560.
