Calculate the LCM of 642,656,358,451,772

Given numbers are 642,656,358,451,772

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

The LCM of 642,656,358,451,772 is 80022459792.

Find LCM of 642,656,358,451,772 with Prime Factorization


2 642, 656, 358, 451, 772
2 321, 328, 179, 451, 386
41 321, 164, 179, 451, 193
321, 4, 179, 11, 193

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

2 x 2 x 41 x 321 x 4 x 179 x 11 x 193 = 80022459792

Therefore, the lowest common multiple of 642,656,358,451,772 is 80022459792.

LCM Formula to Find Lowest Common Multiple of 642,656,358,451,772

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.

642 x 656 x 358 x 451 x 772 = 52494733623552

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

358 : 1, 2, 179, 358

451 : 1, 11, 41, 451

772 : 1, 2, 4, 193, 386, 772

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,656,358,451,772, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

656:2x 2x 2x 2x 41

358:2x 179

451:11x 41

772:2x 2x 193

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 = 52494733623552/(1x656)

LCM = 52494733623552/656

LCM = 80022459792

Thus, we can understand that the LCM of 642,656,358,451,772 is 80022459792.
