Given numbers are 644,529,272,257

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

The LCM of 644,529,272,257 is 258854512.

Find LCM of 644,529,272,257 with Prime Factorization

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

2 x 2 x 23 x 7 x 23 x 68 x 257 = 258854512

Therefore, the lowest common multiple of 644,529,272,257 is 258854512.

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.

644 x 529 x 272 x 257 = 23814615104

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

529 : 1, 23, 529

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,529,272,257, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

529:23x 23

272:2x 2x 2x 2x 17

257:257

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 23 = 92

Therefore, the value for common factors is 92.

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 = 23814615104/(1x92)

LCM = 23814615104/92

LCM = 258854512

Thus, we can understand that the LCM of 644,529,272,257 is 258854512.
