Calculate the LCM of 624,390,604

Given numbers are 624,390,604

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

The LCM of 624,390,604 is 471120.

Find LCM of 624,390,604 with Prime Factorization


2 624, 390, 604
2 312, 195, 302
3 156, 195, 151
13 52, 65, 151
4, 5, 151

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

2 x 2 x 3 x 13 x 4 x 5 x 151 = 471120

Therefore, the lowest common multiple of 624,390,604 is 471120.

LCM Formula to Find Lowest Common Multiple of 624,390,604

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 390 x 604 = 146989440

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

604 : 1, 2, 4, 151, 302, 604

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,390,604, is 2.

Now, the common factors can be found like this.

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

390:2x 3x 5x 13

604:2x 2x 151

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 = 146989440/(2x156)

LCM = 146989440/312

LCM = 471120

Thus, we can understand that the LCM of 624,390,604 is 471120.
