Calculate the LCM of 308,771,843,438

Given numbers are 308,771,843,438

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

The LCM of 308,771,843,438 is 4871181084.

Find LCM of 308,771,843,438 with Prime Factorization


2 308, 771, 843, 438
3 154, 771, 843, 219
154, 257, 281, 73

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

2 x 3 x 154 x 257 x 281 x 73 = 4871181084

Therefore, the lowest common multiple of 308,771,843,438 is 4871181084.

LCM Formula to Find Lowest Common Multiple of 308,771,843,438

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.

308 x 771 x 843 x 438 = 87681259512

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.

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

771 : 1, 3, 257, 771

843 : 1, 3, 281, 843

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,771,843,438, is 1.

Now, the common factors can be found like this.

308:2x 2x 7x 11

771:3x 257

843:3x 281

438:2x 3x 73

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 3 = 18

Therefore, the value for common factors is 18.

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 = 87681259512/(1x18)

LCM = 87681259512/18

LCM = 4871181084

Thus, we can understand that the LCM of 308,771,843,438 is 4871181084.
