Calculate the LCM of 961,646,936,442

Given numbers are 961,646,936,442

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

The LCM of 961,646,936,442 is 290537208.

Find LCM of 961,646,936,442 with Prime Factorization


2 961, 646, 936, 442
13 961, 323, 468, 221
17 961, 323, 36, 17
961, 19, 36, 1

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

2 x 13 x 17 x 961 x 19 x 36 x 1 = 290537208

Therefore, the lowest common multiple of 961,646,936,442 is 290537208.

LCM Formula to Find Lowest Common Multiple of 961,646,936,442

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.

961 x 646 x 936 x 442 = 256834891872

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.

961 : 1, 31, 961

646 : 1, 2, 17, 19, 34, 38, 323, 646

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,646,936,442, is 1.

Now, the common factors can be found like this.

961:31x 31

646:2x 17x 19

936:2x 2x 2x 3x 3x 13

442:2x 13x 17

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 13x 17 = 884

Therefore, the value for common factors is 884.

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 = 256834891872/(1x884)

LCM = 256834891872/884

LCM = 290537208

Thus, we can understand that the LCM of 961,646,936,442 is 290537208.
