Given numbers are 277,299,280,138

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

The LCM of 277,299,280,138 is 69571320.

Find LCM of 277,299,280,138 with Prime Factorization

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

2 x 23 x 277 x 13 x 140 x 3 = 69571320

Therefore, the lowest common multiple of 277,299,280,138 is 69571320.

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.

277 x 299 x 280 x 138 = 3200280720

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.

277 : 1, 277

299 : 1, 13, 23, 299

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,299,280,138, is 1.

Now, the common factors can be found like this.

277:277

299:13x 23

280:2x 2x 2x 5x 7

138:2x 3x 23

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 3200280720/(1x46)

LCM = 3200280720/46

LCM = 69571320

Thus, we can understand that the LCM of 277,299,280,138 is 69571320.

Here are some samples of LCM of two or more Numbers calculations.
