Calculate the LCM of 257,338,620,492

Given numbers are 257,338,620,492

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

The LCM of 257,338,620,492 is 3312200580.

Find LCM of 257,338,620,492 with Prime Factorization


2 257, 338, 620, 492
2 257, 169, 310, 246
257, 169, 155, 123

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

2 x 2 x 257 x 169 x 155 x 123 = 3312200580

Therefore, the lowest common multiple of 257,338,620,492 is 3312200580.

LCM Formula to Find Lowest Common Multiple of 257,338,620,492

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.

257 x 338 x 620 x 492 = 26497604640

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.

257 : 1, 257

338 : 1, 2, 13, 26, 169, 338

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,338,620,492, is 1.

Now, the common factors can be found like this.

257:257

338:2x 13x 13

620:2x 2x 5x 31

492:2x 2x 3x 41

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 2 = 8

Therefore, the value for common factors is 8.

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 = 26497604640/(1x8)

LCM = 26497604640/8

LCM = 3312200580

Thus, we can understand that the LCM of 257,338,620,492 is 3312200580.
