Given numbers are 689,557,872,428

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

The LCM of 689,557,872,428 is 35807555992.

Find LCM of 689,557,872,428 with Prime Factorization

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

2 x 2 x 689 x 557 x 218 x 107 = 35807555992

Therefore, the lowest common multiple of 689,557,872,428 is 35807555992.

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.

689 x 557 x 872 x 428 = 143230223968

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.

689 : 1, 13, 53, 689

557 : 1, 557

872 : 1, 2, 4, 8, 109, 218, 436, 872

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,557,872,428, is 1.

Now, the common factors can be found like this.

689:13x 53

557:557

872:2x 2x 2x 109

428:2x 2x 107

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 = 143230223968/(1x4)

LCM = 143230223968/4

LCM = 35807555992

Thus, we can understand that the LCM of 689,557,872,428 is 35807555992.
