Given numbers are 815,227,619,681

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

The LCM of 815,227,619,681 is 343554285.

Find LCM of 815,227,619,681 with Prime Factorization

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

227 x 815 x 1 x 619 x 3 = 343554285

Therefore, the lowest common multiple of 815,227,619,681 is 343554285.

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 227 x 619 x 681 = 77986822695

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

227 : 1, 227

619 : 1, 619

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,227,619,681, is 1.

Now, the common factors can be found like this.

815:5x 163

227:227

619:619

681:3x 227

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

227 = 227

Therefore, the value for common factors is 227.

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 = 77986822695/(1x227)

LCM = 77986822695/227

LCM = 343554285

Thus, we can understand that the LCM of 815,227,619,681 is 343554285.
