Calculate the LCM of 555,969,969,756

Given numbers are 555,969,969,756

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

The LCM of 555,969,969,756 is 45174780.

Find LCM of 555,969,969,756 with Prime Factorization


3 555, 969, 969, 756
17 185, 323, 323, 252
19 185, 19, 19, 252
185, 1, 1, 252

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

3 x 17 x 19 x 185 x 1 x 1 x 252 = 45174780

Therefore, the lowest common multiple of 555,969,969,756 is 45174780.

LCM Formula to Find Lowest Common Multiple of 555,969,969,756

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.

555 x 969 x 969 x 756 = 393969256380

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

969 : 1, 3, 17, 19, 51, 57, 323, 969

969 : 1, 3, 17, 19, 51, 57, 323, 969

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,969,969,756, is 3.

Now, the common factors can be found like this.

555:3x 5x 37

969:3x 17x 19

969:3x 17x 19

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

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 17x 19 = 2907

Therefore, the value for common factors is 2907.

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 = 393969256380/(3x2907)

LCM = 393969256380/8721

LCM = 45174780

Thus, we can understand that the LCM of 555,969,969,756 is 45174780.
