Given numbers are 986,257,698,561

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

The LCM of 986,257,698,561 is 2918430834.

Find LCM of 986,257,698,561 with Prime Factorization

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

2 x 17 x 29 x 257 x 349 x 33 = 2918430834

Therefore, the lowest common multiple of 986,257,698,561 is 2918430834.

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.

986 x 257 x 698 x 561 = 99226648356

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.

986 : 1, 2, 17, 29, 34, 58, 493, 986

257 : 1, 257

698 : 1, 2, 349, 698

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,257,698,561, is 1.

Now, the common factors can be found like this.

986:2x 17x 29

257:257

698:2x 349

561:3x 11x 17

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 99226648356/(1x34)

LCM = 99226648356/34

LCM = 2918430834

Thus, we can understand that the LCM of 986,257,698,561 is 2918430834.
