Find LCM of 378,420,440,593 with Prime Factorization


2 378, 420, 440, 593
2 189, 210, 220, 593
3 189, 105, 110, 593
5 63, 35, 110, 593
7 63, 7, 22, 593
9, 1, 22, 593

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

2 x 2 x 3 x 5 x 7 x 9 x 1 x 22 x 593 = 49313880

Therefore, the lowest common multiple of 378,420,440,593 is 49313880.

LCM Formula to Find Lowest Common Multiple of 378,420,440,593

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.

378 x 420 x 440 x 593 = 41423659200

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.

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

593 : 1, 593

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,420,440,593, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

420:2x 2x 3x 5x 7

440:2x 2x 2x 5x 11

593:593

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 2x 3x 5x 7 = 840

Therefore, the value for common factors is 840.

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 = 41423659200/(1x840)

LCM = 41423659200/840

LCM = 49313880

Thus, we can understand that the LCM of 378,420,440,593 is 49313880.
