Calculate the LCM of 969,642,981,784

Given numbers are 969,642,981,784

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

The LCM of 969,642,981,784 is 26581003344.

Find LCM of 969,642,981,784 with Prime Factorization


2 969, 642, 981, 784
3 969, 321, 981, 392
323, 107, 327, 392

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

2 x 3 x 323 x 107 x 327 x 392 = 26581003344

Therefore, the lowest common multiple of 969,642,981,784 is 26581003344.

LCM Formula to Find Lowest Common Multiple of 969,642,981,784

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.

969 x 642 x 981 x 784 = 478458060192

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.

969 : 1, 3, 17, 19, 51, 57, 323, 969

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,642,981,784, is 1.

Now, the common factors can be found like this.

969:3x 17x 19

642:2x 3x 107

981:3x 3x 109

784:2x 2x 2x 2x 7x 7

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 478458060192/(1x18)

LCM = 478458060192/18

LCM = 26581003344

Thus, we can understand that the LCM of 969,642,981,784 is 26581003344.
