Given numbers are 257,689,494

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

The LCM of 257,689,494 is 6728774.

Find LCM of 257,689,494 with Prime Factorization

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

13 x 257 x 53 x 38 = 6728774

Therefore, the lowest common multiple of 257,689,494 is 6728774.

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 689 x 494 = 87474062

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

689 : 1, 13, 53, 689

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,689,494, is 1.

Now, the common factors can be found like this.

257:257

689:13x 53

494:2x 13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 87474062/(1x13)

LCM = 87474062/13

LCM = 6728774

Thus, we can understand that the LCM of 257,689,494 is 6728774.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 724, 571, 180
• LCM of 416, 786, 808
