Calculate the LCM of 981,766,109,668

Given numbers are 981,766,109,668

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

The LCM of 981,766,109,668 is 250982964.

Find LCM of 981,766,109,668 with Prime Factorization


2 981, 766, 109, 668
109 981, 383, 109, 334
9, 383, 1, 334

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

2 x 109 x 9 x 383 x 1 x 334 = 250982964

Therefore, the lowest common multiple of 981,766,109,668 is 250982964.

LCM Formula to Find Lowest Common Multiple of 981,766,109,668

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 766 x 109 x 668 = 54714286152

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

766 : 1, 2, 383, 766

109 : 1, 109

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,766,109,668, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

766:2x 383

109:109

668:2x 2x 167

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 54714286152/(1x218)

LCM = 54714286152/218

LCM = 250982964

Thus, we can understand that the LCM of 981,766,109,668 is 250982964.
