Given numbers are 287,257,644,518

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

The LCM of 287,257,644,518 is 251075636.

Find LCM of 287,257,644,518 with Prime Factorization

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

2 x 7 x 41 x 257 x 46 x 37 = 251075636

Therefore, the lowest common multiple of 287,257,644,518 is 251075636.

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.

287 x 257 x 644 x 518 = 24605412328

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.

287 : 1, 7, 41, 287

257 : 1, 257

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

518 : 1, 2, 7, 14, 37, 74, 259, 518

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,257,644,518, is 1.

Now, the common factors can be found like this.

287:7x 41

257:257

644:2x 2x 7x 23

518:2x 7x 37

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 24605412328/(1x98)

LCM = 24605412328/98

LCM = 251075636

Thus, we can understand that the LCM of 287,257,644,518 is 251075636.
