Calculate the LCM of 801,520,816,398

Given numbers are 801,520,816,398

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

The LCM of 801,520,816,398 is 2818174320.

Find LCM of 801,520,816,398 with Prime Factorization


2 801, 520, 816, 398
2 801, 260, 408, 199
2 801, 130, 204, 199
3 801, 65, 102, 199
267, 65, 34, 199

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

2 x 2 x 2 x 3 x 267 x 65 x 34 x 199 = 2818174320

Therefore, the lowest common multiple of 801,520,816,398 is 2818174320.

LCM Formula to Find Lowest Common Multiple of 801,520,816,398

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.

801 x 520 x 816 x 398 = 135272367360

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.

801 : 1, 3, 9, 89, 267, 801

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,520,816,398, is 1.

Now, the common factors can be found like this.

801:3x 3x 89

520:2x 2x 2x 5x 13

816:2x 2x 2x 2x 3x 17

398:2x 199

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 2x 3 = 48

Therefore, the value for common factors is 48.

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 = 135272367360/(1x48)

LCM = 135272367360/48

LCM = 2818174320

Thus, we can understand that the LCM of 801,520,816,398 is 2818174320.
