Calculate the LCM of 261,981,393,404

Given numbers are 261,981,393,404

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

The LCM of 261,981,393,404 is 1505634876.

Find LCM of 261,981,393,404 with Prime Factorization


3 261, 981, 393, 404
3 87, 327, 131, 404
29, 109, 131, 404

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

3 x 3 x 29 x 109 x 131 x 404 = 1505634876

Therefore, the lowest common multiple of 261,981,393,404 is 1505634876.

LCM Formula to Find Lowest Common Multiple of 261,981,393,404

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.

261 x 981 x 393 x 404 = 40652141652

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.

261 : 1, 3, 9, 29, 87, 261

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

393 : 1, 3, 131, 393

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,981,393,404, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

981:3x 3x 109

393:3x 131

404:2x 2x 101

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 40652141652/(1x27)

LCM = 40652141652/27

LCM = 1505634876

Thus, we can understand that the LCM of 261,981,393,404 is 1505634876.
