Given numbers are 691,826,394,298,220

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

The LCM of 691,826,394,298,220 is 1842906383780.

Find LCM of 691,826,394,298,220 with Prime Factorization

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

2 x 691 x 413 x 197 x 149 x 110 = 1842906383780

Therefore, the lowest common multiple of 691,826,394,298,220 is 1842906383780.

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.

691 x 826 x 394 x 298 x 220 = 14743251070240

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.

691 : 1, 691

826 : 1, 2, 7, 14, 59, 118, 413, 826

394 : 1, 2, 197, 394

298 : 1, 2, 149, 298

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,826,394,298,220, is 1.

Now, the common factors can be found like this.

691:691

826:2x 7x 59

394:2x 197

298:2x 149

220:2x 2x 5x 11

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 14743251070240/(1x8)

LCM = 14743251070240/8

LCM = 1842906383780

Thus, we can understand that the LCM of 691,826,394,298,220 is 1842906383780.
