Given numbers are 1,689,642,722

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

The LCM of 1,689,642,722 is 159684018.

Find LCM of 1,689,642,722 with Prime Factorization

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

2 x 1 x 689 x 321 x 361 = 159684018

Therefore, the lowest common multiple of 1,689,642,722 is 159684018.

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.

1 x 689 x 642 x 722 = 319368036

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.

1 : 1

689 : 1, 13, 53, 689

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,689,642,722, is 1.

Now, the common factors can be found like this.

1:

689:13x 53

642:2x 3x 107

722:2x 19x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 319368036/(1x2)

LCM = 319368036/2

LCM = 159684018

Thus, we can understand that the LCM of 1,689,642,722 is 159684018.
