Given numbers are 209,169,278,897

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

The LCM of 209,169,278,897 is 677527422.

Find LCM of 209,169,278,897 with Prime Factorization

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

13 x 209 x 13 x 278 x 69 = 677527422

Therefore, the lowest common multiple of 209,169,278,897 is 677527422.

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 169 x 278 x 897 = 8807856486

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

169 : 1, 13, 169

278 : 1, 2, 139, 278

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,169,278,897, is 1.

Now, the common factors can be found like this.

209:11x 19

169:13x 13

278:2x 139

897:3x 13x 23

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

13 = 13

Therefore, the value for common factors is 13.

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 = 8807856486/(1x13)

LCM = 8807856486/13

LCM = 677527422

Thus, we can understand that the LCM of 209,169,278,897 is 677527422.
