Given numbers are 815,506,218,774

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

The LCM of 815,506,218,774 is 17395847370.

Find LCM of 815,506,218,774 with Prime Factorization

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

2 x 815 x 253 x 109 x 387 = 17395847370

Therefore, the lowest common multiple of 815,506,218,774 is 17395847370.

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.

815 x 506 x 218 x 774 = 69583389480

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.

815 : 1, 5, 163, 815

506 : 1, 2, 11, 22, 23, 46, 253, 506

218 : 1, 2, 109, 218

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,506,218,774, is 1.

Now, the common factors can be found like this.

815:5x 163

506:2x 11x 23

218:2x 109

774:2x 3x 3x 43

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 = 69583389480/(1x4)

LCM = 69583389480/4

LCM = 17395847370

Thus, we can understand that the LCM of 815,506,218,774 is 17395847370.
