Calculate the LCM of 661,738,256,328

Given numbers are 661,738,256,328

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

The LCM of 661,738,256,328 is 62440704.

Find LCM of 661,738,256,328 with Prime Factorization


2 661, 738, 256, 328
2 661, 369, 128, 164
2 661, 369, 64, 82
41 661, 369, 32, 41
661, 9, 32, 1

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

2 x 2 x 2 x 41 x 661 x 9 x 32 x 1 = 62440704

Therefore, the lowest common multiple of 661,738,256,328 is 62440704.

LCM Formula to Find Lowest Common Multiple of 661,738,256,328

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.

661 x 738 x 256 x 328 = 40961101824

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.

661 : 1, 661

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,738,256,328, is 1.

Now, the common factors can be found like this.

661:661

738:2x 3x 3x 41

256:2x 2x 2x 2x 2x 2x 2x 2

328:2x 2x 2x 41

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 2x 41 = 656

Therefore, the value for common factors is 656.

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 = 40961101824/(1x656)

LCM = 40961101824/656

LCM = 62440704

Thus, we can understand that the LCM of 661,738,256,328 is 62440704.
