Given numbers are 254,514,257,647

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

The LCM of 254,514,257,647 is 42234866.

Find LCM of 254,514,257,647 with Prime Factorization

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

2 x 257 x 127 x 1 x 1 x 647 = 42234866

Therefore, the lowest common multiple of 254,514,257,647 is 42234866.

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.

254 x 514 x 257 x 647 = 21708721124

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.

254 : 1, 2, 127, 254

514 : 1, 2, 257, 514

257 : 1, 257

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,514,257,647, is 1.

Now, the common factors can be found like this.

254:2x 127

514:2x 257

257:257

647:647

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

2x 257 = 514

Therefore, the value for common factors is 514.

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 = 21708721124/(1x514)

LCM = 21708721124/514

LCM = 42234866

Thus, we can understand that the LCM of 254,514,257,647 is 42234866.
