Given numbers are 981,919,742,786

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

The LCM of 981,919,742,786 is 87631393878.

Find LCM of 981,919,742,786 with Prime Factorization

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

2 x 3 x 327 x 919 x 371 x 131 = 87631393878

Therefore, the lowest common multiple of 981,919,742,786 is 87631393878.

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.

981 x 919 x 742 x 786 = 525788363268

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.

981 : 1, 3, 9, 109, 327, 981

919 : 1, 919

742 : 1, 2, 7, 14, 53, 106, 371, 742

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,919,742,786, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

919:919

742:2x 7x 53

786:2x 3x 131

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 525788363268/(1x6)

LCM = 525788363268/6

LCM = 87631393878

Thus, we can understand that the LCM of 981,919,742,786 is 87631393878.
