Calculate the LCM of 788,172,642,473

Given numbers are 788,172,642,473

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

The LCM of 788,172,642,473 is 119644404.

Find LCM of 788,172,642,473 with Prime Factorization


2 788, 172, 642, 473
2 394, 86, 321, 473
43 197, 43, 321, 473
197, 1, 321, 11

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

2 x 2 x 43 x 197 x 1 x 321 x 11 = 119644404

Therefore, the lowest common multiple of 788,172,642,473 is 119644404.

LCM Formula to Find Lowest Common Multiple of 788,172,642,473

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.

788 x 172 x 642 x 473 = 41157674976

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.

788 : 1, 2, 4, 197, 394, 788

172 : 1, 2, 4, 43, 86, 172

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

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,172,642,473, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

172:2x 2x 43

642:2x 3x 107

473:11x 43

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 43 = 344

Therefore, the value for common factors is 344.

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 = 41157674976/(1x344)

LCM = 41157674976/344

LCM = 119644404

Thus, we can understand that the LCM of 788,172,642,473 is 119644404.
