Given numbers are 257,257,357

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

The LCM of 257,257,357 is 91749.

Find LCM of 257,257,357 with Prime Factorization

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

257 x 1 x 1 x 357 = 91749

Therefore, the lowest common multiple of 257,257,357 is 91749.

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 257 x 357 = 23579493

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

257 : 1, 257

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,257,357, is 1.

Now, the common factors can be found like this.

257:257

257:257

357:3x 7x 17

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

257 = 257

Therefore, the value for common factors is 257.

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 = 23579493/(1x257)

LCM = 23579493/257

LCM = 91749

Thus, we can understand that the LCM of 257,257,357 is 91749.

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

• LCM of 767, 327, 678
• LCM of 313, 946, 226
