Given numbers are 257,474,772,686

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

The LCM of 257,474,772,686 is 16128459564.

Find LCM of 257,474,772,686 with Prime Factorization

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

2 x 257 x 237 x 386 x 343 = 16128459564

Therefore, the lowest common multiple of 257,474,772,686 is 16128459564.

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 474 x 772 x 686 = 64513838256

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

474 : 1, 2, 3, 6, 79, 158, 237, 474

772 : 1, 2, 4, 193, 386, 772

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,474,772,686, is 1.

Now, the common factors can be found like this.

257:257

474:2x 3x 79

772:2x 2x 193

686:2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 64513838256/(1x4)

LCM = 64513838256/4

LCM = 16128459564

Thus, we can understand that the LCM of 257,474,772,686 is 16128459564.
