Calculate the LCM of 634,642,989,944,374

Given numbers are 634,642,989,944,374

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

The LCM of 634,642,989,944,374 is 17765367139344.

Find LCM of 634,642,989,944,374 with Prime Factorization


2 634, 642, 989, 944, 374
317, 321, 989, 472, 187

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

2 x 317 x 321 x 989 x 472 x 187 = 17765367139344

Therefore, the lowest common multiple of 634,642,989,944,374 is 17765367139344.

LCM Formula to Find Lowest Common Multiple of 634,642,989,944,374

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.

634 x 642 x 989 x 944 x 374 = 142122937114752

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.

634 : 1, 2, 317, 634

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

989 : 1, 23, 43, 989

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

374 : 1, 2, 11, 17, 22, 34, 187, 374

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,642,989,944,374, is 1.

Now, the common factors can be found like this.

634:2x 317

642:2x 3x 107

989:23x 43

944:2x 2x 2x 2x 59

374:2x 11x 17

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 2 = 8

Therefore, the value for common factors is 8.

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 = 142122937114752/(1x8)

LCM = 142122937114752/8

LCM = 17765367139344

Thus, we can understand that the LCM of 634,642,989,944,374 is 17765367139344.
