Calculate the LCM of 626,641,994,450

Given numbers are 626,641,994,450

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

The LCM of 626,641,994,450 is 44871570450.

Find LCM of 626,641,994,450 with Prime Factorization


2 626, 641, 994, 450
313, 641, 497, 225

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

2 x 313 x 641 x 497 x 225 = 44871570450

Therefore, the lowest common multiple of 626,641,994,450 is 44871570450.

LCM Formula to Find Lowest Common Multiple of 626,641,994,450

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.

626 x 641 x 994 x 450 = 179486281800

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.

626 : 1, 2, 313, 626

641 : 1, 641

994 : 1, 2, 7, 14, 71, 142, 497, 994

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,641,994,450, is 1.

Now, the common factors can be found like this.

626:2x 313

641:641

994:2x 7x 71

450:2x 3x 3x 5x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 179486281800/(1x4)

LCM = 179486281800/4

LCM = 44871570450

Thus, we can understand that the LCM of 626,641,994,450 is 44871570450.
