Calculate the LCM of 638,275,577,197

Given numbers are 638,275,577,197

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

The LCM of 638,275,577,197 is 1813020550.

Find LCM of 638,275,577,197 with Prime Factorization


11 638, 275, 577, 197
58, 25, 577, 197

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

11 x 58 x 25 x 577 x 197 = 1813020550

Therefore, the lowest common multiple of 638,275,577,197 is 1813020550.

LCM Formula to Find Lowest Common Multiple of 638,275,577,197

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.

638 x 275 x 577 x 197 = 19943226050

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

275 : 1, 5, 11, 25, 55, 275

577 : 1, 577

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,275,577,197, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

275:5x 5x 11

577:577

197:197

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

11 = 11

Therefore, the value for common factors is 11.

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 = 19943226050/(1x11)

LCM = 19943226050/11

LCM = 1813020550

Thus, we can understand that the LCM of 638,275,577,197 is 1813020550.
