Find LCM of 838,324,378,581 with Prime Factorization


2 838, 324, 378, 581
3 419, 162, 189, 581
3 419, 54, 63, 581
3 419, 18, 21, 581
7 419, 6, 7, 581
419, 6, 1, 83

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

2 x 3 x 3 x 3 x 7 x 419 x 6 x 1 x 83 = 78874236

Therefore, the lowest common multiple of 838,324,378,581 is 78874236.

LCM Formula to Find Lowest Common Multiple of 838,324,378,581

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.

838 x 324 x 378 x 581 = 59628922416

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.

838 : 1, 2, 419, 838

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

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

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,324,378,581, is 1.

Now, the common factors can be found like this.

838:2x 419

324:2x 2x 3x 3x 3x 3

378:2x 3x 3x 3x 7

581:7x 83

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 3x 3x 7 = 756

Therefore, the value for common factors is 756.

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 = 59628922416/(1x756)

LCM = 59628922416/756

LCM = 78874236

Thus, we can understand that the LCM of 838,324,378,581 is 78874236.
