Calculate the LCM of 831,372,474,279

Given numbers are 831,372,474,279

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

The LCM of 831,372,474,279 is 24421428.

Find LCM of 831,372,474,279 with Prime Factorization


2 831, 372, 474, 279
3 831, 186, 237, 279
31 277, 62, 79, 93
277, 2, 79, 3

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

2 x 3 x 31 x 277 x 2 x 79 x 3 = 24421428

Therefore, the lowest common multiple of 831,372,474,279 is 24421428.

LCM Formula to Find Lowest Common Multiple of 831,372,474,279

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 372 x 474 x 279 = 40881470472

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

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

474 : 1, 2, 3, 6, 79, 158, 237, 474

279 : 1, 3, 9, 31, 93, 279

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,372,474,279, is 3.

Now, the common factors can be found like this.

831:3x 277

372:2x 2x 3x 31

474:2x 3x 79

279:3x 3x 31

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

2x 3x 3x 31 = 558

Therefore, the value for common factors is 558.

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 = 40881470472/(3x558)

LCM = 40881470472/1674

LCM = 24421428

Thus, we can understand that the LCM of 831,372,474,279 is 24421428.
