Given numbers are 798,188,430,257

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

The LCM of 798,188,430,257 is 4144788060.

Find LCM of 798,188,430,257 with Prime Factorization

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

2 x 399 x 94 x 215 x 257 = 4144788060

Therefore, the lowest common multiple of 798,188,430,257 is 4144788060.

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.

798 x 188 x 430 x 257 = 16579152240

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

188 : 1, 2, 4, 47, 94, 188

430 : 1, 2, 5, 10, 43, 86, 215, 430

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,188,430,257, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

188:2x 2x 47

430:2x 5x 43

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 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 = 16579152240/(1x4)

LCM = 16579152240/4

LCM = 4144788060

Thus, we can understand that the LCM of 798,188,430,257 is 4144788060.
