Calculate the LCM of 753,705,389

Given numbers are 753,705,389

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

The LCM of 753,705,389 is 68835495.

Find LCM of 753,705,389 with Prime Factorization


3 753, 705, 389
251, 235, 389

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

3 x 251 x 235 x 389 = 68835495

Therefore, the lowest common multiple of 753,705,389 is 68835495.

LCM Formula to Find Lowest Common Multiple of 753,705,389

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.

753 x 705 x 389 = 206506485

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.

753 : 1, 3, 251, 753

705 : 1, 3, 5, 15, 47, 141, 235, 705

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,705,389, is 1.

Now, the common factors can be found like this.

753:3x 251

705:3x 5x 47

389:389

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 = 206506485/(1x3)

LCM = 206506485/3

LCM = 68835495

Thus, we can understand that the LCM of 753,705,389 is 68835495.
