Calculate the LCM of 831,763,399,363

Given numbers are 831,763,399,363

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

The LCM of 831,763,399,363 is 1457687847.

Find LCM of 831,763,399,363 with Prime Factorization


3 831, 763, 399, 363
7 277, 763, 133, 121
277, 109, 19, 121

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

3 x 7 x 277 x 109 x 19 x 121 = 1457687847

Therefore, the lowest common multiple of 831,763,399,363 is 1457687847.

LCM Formula to Find Lowest Common Multiple of 831,763,399,363

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.

831 x 763 x 399 x 363 = 91834334361

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.

831 : 1, 3, 277, 831

763 : 1, 7, 109, 763

399 : 1, 3, 7, 19, 21, 57, 133, 399

363 : 1, 3, 11, 33, 121, 363

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,763,399,363, is 1.

Now, the common factors can be found like this.

831:3x 277

763:7x 109

399:3x 7x 19

363:3x 11x 11

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

3x 3x 7 = 63

Therefore, the value for common factors is 63.

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 = 91834334361/(1x63)

LCM = 91834334361/63

LCM = 1457687847

Thus, we can understand that the LCM of 831,763,399,363 is 1457687847.
