Given numbers are 681,404,917,909

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

The LCM of 681,404,917,909 is 756866124.

Find LCM of 681,404,917,909 with Prime Factorization

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

3 x 101 x 227 x 4 x 917 x 3 = 756866124

Therefore, the lowest common multiple of 681,404,917,909 is 756866124.

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.

681 x 404 x 917 x 909 = 229330435572

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.

681 : 1, 3, 227, 681

404 : 1, 2, 4, 101, 202, 404

917 : 1, 7, 131, 917

909 : 1, 3, 9, 101, 303, 909

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,404,917,909, is 1.

Now, the common factors can be found like this.

681:3x 227

404:2x 2x 101

917:7x 131

909:3x 3x 101

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

3x 101 = 303

Therefore, the value for common factors is 303.

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 = 229330435572/(1x303)

LCM = 229330435572/303

LCM = 756866124

Thus, we can understand that the LCM of 681,404,917,909 is 756866124.
