Given numbers are 257,436,697,218

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

The LCM of 257,436,697,218 is 78100244.

Find LCM of 257,436,697,218 with Prime Factorization

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

2 x 109 x 257 x 2 x 697 x 1 = 78100244

Therefore, the lowest common multiple of 257,436,697,218 is 78100244.

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 436 x 697 x 218 = 17025853192

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

436 : 1, 2, 4, 109, 218, 436

697 : 1, 17, 41, 697

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,436,697,218, is 1.

Now, the common factors can be found like this.

257:257

436:2x 2x 109

697:17x 41

218:2x 109

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 17025853192/(1x218)

LCM = 17025853192/218

LCM = 78100244

Thus, we can understand that the LCM of 257,436,697,218 is 78100244.
