Given numbers are 340,986,672,660,257

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

The LCM of 340,986,672,660,257 is 4682868960.

Find LCM of 340,986,672,660,257 with Prime Factorization

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

2 x 2 x 3 x 5 x 17 x 1 x 29 x 56 x 11 x 257 = 4682868960

Therefore, the lowest common multiple of 340,986,672,660,257 is 4682868960.

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.

340 x 986 x 672 x 660 x 257 = 38212210713600

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.

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

986 : 1, 2, 17, 29, 34, 58, 493, 986

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,986,672,660,257, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

986:2x 17x 29

672:2x 2x 2x 2x 2x 3x 7

660:2x 2x 3x 5x 11

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 2x 2x 2x 3x 5x 17 = 8160

Therefore, the value for common factors is 8160.

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 = 38212210713600/(1x8160)

LCM = 38212210713600/8160

LCM = 4682868960

Thus, we can understand that the LCM of 340,986,672,660,257 is 4682868960.
