Calculate the LCM of 756,515,387,993

Given numbers are 756,515,387,993

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

The LCM of 756,515,387,993 is 5541476220.

Find LCM of 756,515,387,993 with Prime Factorization


3 756, 515, 387, 993
3 252, 515, 129, 331
84, 515, 43, 331

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

3 x 3 x 84 x 515 x 43 x 331 = 5541476220

Therefore, the lowest common multiple of 756,515,387,993 is 5541476220.

LCM Formula to Find Lowest Common Multiple of 756,515,387,993

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.

756 x 515 x 387 x 993 = 149619857940

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.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

515 : 1, 5, 103, 515

387 : 1, 3, 9, 43, 129, 387

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,515,387,993, is 1.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

515:5x 103

387:3x 3x 43

993:3x 331

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 149619857940/(1x27)

LCM = 149619857940/27

LCM = 5541476220

Thus, we can understand that the LCM of 756,515,387,993 is 5541476220.
