Calculate the LCM of 771,214,252,343

Given numbers are 771,214,252,343

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

The LCM of 771,214,252,343 is 339557652.

Find LCM of 771,214,252,343 with Prime Factorization


2 771, 214, 252, 343
3 771, 107, 126, 343
7 257, 107, 42, 343
257, 107, 6, 49

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

2 x 3 x 7 x 257 x 107 x 6 x 49 = 339557652

Therefore, the lowest common multiple of 771,214,252,343 is 339557652.

LCM Formula to Find Lowest Common Multiple of 771,214,252,343

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.

771 x 214 x 252 x 343 = 14261421384

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.

771 : 1, 3, 257, 771

214 : 1, 2, 107, 214

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,214,252,343, is 1.

Now, the common factors can be found like this.

771:3x 257

214:2x 107

252:2x 2x 3x 3x 7

343:7x 7x 7

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 7 = 42

Therefore, the value for common factors is 42.

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 = 14261421384/(1x42)

LCM = 14261421384/42

LCM = 339557652

Thus, we can understand that the LCM of 771,214,252,343 is 339557652.
