Given numbers are 685,252,169,194,218

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

The LCM of 685,252,169,194,218 is 308443802940.

Find LCM of 685,252,169,194,218 with Prime Factorization

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

2 x 685 x 126 x 169 x 97 x 109 = 308443802940

Therefore, the lowest common multiple of 685,252,169,194,218 is 308443802940.

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.

685 x 252 x 169 x 194 x 218 = 1233775211760

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.

685 : 1, 5, 137, 685

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

169 : 1, 13, 169

194 : 1, 2, 97, 194

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,252,169,194,218, is 1.

Now, the common factors can be found like this.

685:5x 137

252:2x 2x 3x 3x 7

169:13x 13

194:2x 97

218:2x 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 = 1233775211760/(1x4)

LCM = 1233775211760/4

LCM = 308443802940

Thus, we can understand that the LCM of 685,252,169,194,218 is 308443802940.
