Given numbers are 681,489,815,776

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

The LCM of 681,489,815,776 is 430691640.

Find LCM of 681,489,815,776 with Prime Factorization

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

3 x 163 x 227 x 1 x 5 x 776 = 430691640

Therefore, the lowest common multiple of 681,489,815,776 is 430691640.

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 489 x 815 x 776 = 210608211960

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

489 : 1, 3, 163, 489

815 : 1, 5, 163, 815

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,489,815,776, is 1.

Now, the common factors can be found like this.

681:3x 227

489:3x 163

815:5x 163

776:2x 2x 2x 97

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

3x 163 = 489

Therefore, the value for common factors is 489.

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 = 210608211960/(1x489)

LCM = 210608211960/489

LCM = 430691640

Thus, we can understand that the LCM of 681,489,815,776 is 430691640.
