Calculate the LCM of 686,981,594,962

Given numbers are 686,981,594,962

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

The LCM of 686,981,594,962 is 10681989318.

Find LCM of 686,981,594,962 with Prime Factorization


2 686, 981, 594, 962
3 343, 981, 297, 481
3 343, 327, 99, 481
343, 109, 33, 481

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

2 x 3 x 3 x 343 x 109 x 33 x 481 = 10681989318

Therefore, the lowest common multiple of 686,981,594,962 is 10681989318.

LCM Formula to Find Lowest Common Multiple of 686,981,594,962

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.

686 x 981 x 594 x 962 = 384551615448

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

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

594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594

962 : 1, 2, 13, 26, 37, 74, 481, 962

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,981,594,962, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

981:3x 3x 109

594:2x 3x 3x 3x 11

962:2x 13x 37

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 384551615448/(1x36)

LCM = 384551615448/36

LCM = 10681989318

Thus, we can understand that the LCM of 686,981,594,962 is 10681989318.
