Calculate the LCM of 981,956,981,291

Given numbers are 981,956,981,291

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

The LCM of 981,956,981,291 is 90970092.

Find LCM of 981,956,981,291 with Prime Factorization


3 981, 956, 981, 291
3 327, 956, 327, 97
109 109, 956, 109, 97
1, 956, 1, 97

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

3 x 3 x 109 x 1 x 956 x 1 x 97 = 90970092

Therefore, the lowest common multiple of 981,956,981,291 is 90970092.

LCM Formula to Find Lowest Common Multiple of 981,956,981,291

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 956 x 981 x 291 = 267724980756

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

956 : 1, 2, 4, 239, 478, 956

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

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,956,981,291, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

956:2x 2x 239

981:3x 3x 109

291:3x 97

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 3x 109 = 2943

Therefore, the value for common factors is 2943.

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 = 267724980756/(1x2943)

LCM = 267724980756/2943

LCM = 90970092

Thus, we can understand that the LCM of 981,956,981,291 is 90970092.
