Given numbers are 686,202,678,187

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

The LCM of 686,202,678,187 is 4392247398.

Find LCM of 686,202,678,187 with Prime Factorization

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

2 x 343 x 101 x 339 x 187 = 4392247398

Therefore, the lowest common multiple of 686,202,678,187 is 4392247398.

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.

686 x 202 x 678 x 187 = 17568989592

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.

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

202 : 1, 2, 101, 202

678 : 1, 2, 3, 6, 113, 226, 339, 678

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,202,678,187, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

202:2x 101

678:2x 3x 113

187:11x 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 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 = 17568989592/(1x4)

LCM = 17568989592/4

LCM = 4392247398

Thus, we can understand that the LCM of 686,202,678,187 is 4392247398.
