Calculate the LCM of 624,330,442,983

Given numbers are 624,330,442,983

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

The LCM of 624,330,442,983 is 573521520.

Find LCM of 624,330,442,983 with Prime Factorization


2 624, 330, 442, 983
3 312, 165, 221, 983
13 104, 55, 221, 983
8, 55, 17, 983

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

2 x 3 x 13 x 8 x 55 x 17 x 983 = 573521520

Therefore, the lowest common multiple of 624,330,442,983 is 573521520.

LCM Formula to Find Lowest Common Multiple of 624,330,442,983

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.

624 x 330 x 442 x 983 = 89469357120

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.

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

442 : 1, 2, 13, 17, 26, 34, 221, 442

983 : 1, 983

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,330,442,983, is 1.

Now, the common factors can be found like this.

624:2x 2x 2x 2x 3x 13

330:2x 3x 5x 11

442:2x 13x 17

983:983

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

2x 2x 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 89469357120/(1x156)

LCM = 89469357120/156

LCM = 573521520

Thus, we can understand that the LCM of 624,330,442,983 is 573521520.
