Given numbers are 281,306,771,142

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

The LCM of 281,306,771,142 is 1568986542.

Find LCM of 281,306,771,142 with Prime Factorization

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

2 x 3 x 281 x 51 x 257 x 71 = 1568986542

Therefore, the lowest common multiple of 281,306,771,142 is 1568986542.

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.

281 x 306 x 771 x 142 = 9413919252

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.

281 : 1, 281

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

771 : 1, 3, 257, 771

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,306,771,142, is 1.

Now, the common factors can be found like this.

281:281

306:2x 3x 3x 17

771:3x 257

142:2x 71

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 9413919252/(1x6)

LCM = 9413919252/6

LCM = 1568986542

Thus, we can understand that the LCM of 281,306,771,142 is 1568986542.
