Calculate the LCM of 891,294,220,752

Given numbers are 891,294,220,752

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

The LCM of 891,294,220,752 is 164157840.

Find LCM of 891,294,220,752 with Prime Factorization


2 891, 294, 220, 752
2 891, 147, 110, 376
3 891, 147, 55, 188
11 297, 49, 55, 188
27, 49, 5, 188

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

2 x 2 x 3 x 11 x 27 x 49 x 5 x 188 = 164157840

Therefore, the lowest common multiple of 891,294,220,752 is 164157840.

LCM Formula to Find Lowest Common Multiple of 891,294,220,752

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.

891 x 294 x 220 x 752 = 43337669760

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,294,220,752, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

294:2x 3x 7x 7

220:2x 2x 5x 11

752:2x 2x 2x 2x 47

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 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 43337669760/(1x264)

LCM = 43337669760/264

LCM = 164157840

Thus, we can understand that the LCM of 891,294,220,752 is 164157840.
