Given numbers are 781,167,378,939,681

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

The LCM of 781,167,378,939,681 is 3502914197706.

Find LCM of 781,167,378,939,681 with Prime Factorization

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

3 x 781 x 167 x 126 x 313 x 227 = 3502914197706

Therefore, the lowest common multiple of 781,167,378,939,681 is 3502914197706.

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.

781 x 167 x 378 x 939 x 681 = 31526227779354

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.

781 : 1, 11, 71, 781

167 : 1, 167

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

939 : 1, 3, 313, 939

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,167,378,939,681, is 1.

Now, the common factors can be found like this.

781:11x 71

167:167

378:2x 3x 3x 3x 7

939:3x 313

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 31526227779354/(1x9)

LCM = 31526227779354/9

LCM = 3502914197706

Thus, we can understand that the LCM of 781,167,378,939,681 is 3502914197706.
