The LCM of 644,656,451,297 is 31367952.

Find LCM of 644,656,451,297 with Prime Factorization


2 644, 656, 451, 297
2 322, 328, 451, 297
11 161, 164, 451, 297
41 161, 164, 41, 27
161, 4, 1, 27

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

2 x 2 x 11 x 41 x 161 x 4 x 1 x 27 = 31367952

Therefore, the lowest common multiple of 644,656,451,297 is 31367952.

LCM Formula to Find Lowest Common Multiple of 644,656,451,297

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.

644 x 656 x 451 x 297 = 56587785408

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

451 : 1, 11, 41, 451

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,656,451,297, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

656:2x 2x 2x 2x 41

451:11x 41

297:3x 3x 3x 11

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 11x 41 = 1804

Therefore, the value for common factors is 1804.

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 = 56587785408/(1x1804)

LCM = 56587785408/1804

LCM = 31367952

Thus, we can understand that the LCM of 644,656,451,297 is 31367952.
