Given numbers are 786,717,731,434,681

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

The LCM of 786,717,731,434,681 is 6764308635966.

Find LCM of 786,717,731,434,681 with Prime Factorization

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

2 x 3 x 131 x 239 x 731 x 217 x 227 = 6764308635966

Therefore, the lowest common multiple of 786,717,731,434,681 is 6764308635966.

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.

786 x 717 x 731 x 434 x 681 = 121757555447388

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

717 : 1, 3, 239, 717

731 : 1, 17, 43, 731

434 : 1, 2, 7, 14, 31, 62, 217, 434

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,717,731,434,681, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

717:3x 239

731:17x 43

434:2x 7x 31

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.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 121757555447388/(1x18)

LCM = 121757555447388/18

LCM = 6764308635966

Thus, we can understand that the LCM of 786,717,731,434,681 is 6764308635966.
