Given numbers are 209,686,498,436

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

The LCM of 209,686,498,436 is 7782627468.

Find LCM of 209,686,498,436 with Prime Factorization

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

2 x 209 x 343 x 249 x 218 = 7782627468

Therefore, the lowest common multiple of 209,686,498,436 is 7782627468.

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.

209 x 686 x 498 x 436 = 31130509872

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.

209 : 1, 11, 19, 209

686 : 1, 2, 7, 14, 49, 98, 343, 686

498 : 1, 2, 3, 6, 83, 166, 249, 498

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,686,498,436, is 1.

Now, the common factors can be found like this.

209:11x 19

686:2x 7x 7x 7

498:2x 3x 83

436:2x 2x 109

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 = 31130509872/(1x4)

LCM = 31130509872/4

LCM = 7782627468

Thus, we can understand that the LCM of 209,686,498,436 is 7782627468.
