Calculate the LCM of 789,645,209,521,512

Given numbers are 789,645,209,521,512

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

The LCM of 789,645,209,521,512 is 9457349383680.

Find LCM of 789,645,209,521,512 with Prime Factorization


3 789, 645, 209, 521, 512
263, 215, 209, 521, 512

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

3 x 263 x 215 x 209 x 521 x 512 = 9457349383680

Therefore, the lowest common multiple of 789,645,209,521,512 is 9457349383680.

LCM Formula to Find Lowest Common Multiple of 789,645,209,521,512

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.

789 x 645 x 209 x 521 x 512 = 28372048151040

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.

789 : 1, 3, 263, 789

645 : 1, 3, 5, 15, 43, 129, 215, 645

209 : 1, 11, 19, 209

521 : 1, 521

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,645,209,521,512, is 1.

Now, the common factors can be found like this.

789:3x 263

645:3x 5x 43

209:11x 19

521:521

512:2x 2x 2x 2x 2x 2x 2x 2x 2

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

3 = 3

Therefore, the value for common factors is 3.

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 = 28372048151040/(1x3)

LCM = 28372048151040/3

LCM = 9457349383680

Thus, we can understand that the LCM of 789,645,209,521,512 is 9457349383680.
