The LCM of 617,456,368,644 is 90595344.

Find LCM of 617,456,368,644 with Prime Factorization


2 617, 456, 368, 644
2 617, 228, 184, 322
2 617, 114, 92, 161
23 617, 57, 46, 161
617, 57, 2, 7

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

2 x 2 x 2 x 23 x 617 x 57 x 2 x 7 = 90595344

Therefore, the lowest common multiple of 617,456,368,644 is 90595344.

LCM Formula to Find Lowest Common Multiple of 617,456,368,644

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.

617 x 456 x 368 x 644 = 66678173184

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.

617 : 1, 617

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,456,368,644, is 1.

Now, the common factors can be found like this.

617:617

456:2x 2x 2x 3x 19

368:2x 2x 2x 2x 23

644:2x 2x 7x 23

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 2x 23 = 736

Therefore, the value for common factors is 736.

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 = 66678173184/(1x736)

LCM = 66678173184/736

LCM = 90595344

Thus, we can understand that the LCM of 617,456,368,644 is 90595344.
