Given numbers are 681,115,790,767,842

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

The LCM of 681,115,790,767,842 is 3995576949390.

Find LCM of 681,115,790,767,842 with Prime Factorization

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

2 x 5 x 681 x 23 x 79 x 767 x 421 = 3995576949390

Therefore, the lowest common multiple of 681,115,790,767,842 is 3995576949390.

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 115 x 790 x 767 x 842 = 39955769493900

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

115 : 1, 5, 23, 115

790 : 1, 2, 5, 10, 79, 158, 395, 790

767 : 1, 13, 59, 767

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,115,790,767,842, is 1.

Now, the common factors can be found like this.

681:3x 227

115:5x 23

790:2x 5x 79

767:13x 59

842:2x 421

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 39955769493900/(1x10)

LCM = 39955769493900/10

LCM = 3995576949390

Thus, we can understand that the LCM of 681,115,790,767,842 is 3995576949390.
