Given numbers are 1,516,242,689

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

The LCM of 1,516,242,689 is 43018404.

Find LCM of 1,516,242,689 with Prime Factorization

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

2 x 1 x 258 x 121 x 689 = 43018404

Therefore, the lowest common multiple of 1,516,242,689 is 43018404.

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 516 x 242 x 689 = 86036808

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

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

242 : 1, 2, 11, 22, 121, 242

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,516,242,689, is 1.

Now, the common factors can be found like this.

1:

516:2x 2x 3x 43

242:2x 11x 11

689:13x 53

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 = 86036808/(1x2)

LCM = 86036808/2

LCM = 43018404

Thus, we can understand that the LCM of 1,516,242,689 is 43018404.
