Given numbers are 698,217,404,637

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

The LCM of 698,217,404,637 is 2784248012.

Find LCM of 698,217,404,637 with Prime Factorization

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

2 x 7 x 349 x 31 x 202 x 91 = 2784248012

Therefore, the lowest common multiple of 698,217,404,637 is 2784248012.

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.

698 x 217 x 404 x 637 = 38979472168

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.

698 : 1, 2, 349, 698

217 : 1, 7, 31, 217

404 : 1, 2, 4, 101, 202, 404

637 : 1, 7, 13, 49, 91, 637

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,217,404,637, is 1.

Now, the common factors can be found like this.

698:2x 349

217:7x 31

404:2x 2x 101

637:7x 7x 13

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 38979472168/(1x14)

LCM = 38979472168/14

LCM = 2784248012

Thus, we can understand that the LCM of 698,217,404,637 is 2784248012.
