Given numbers are 280,334,138

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

The LCM of 280,334,138 is 3226440.

Find LCM of 280,334,138 with Prime Factorization

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

2 x 140 x 167 x 69 = 3226440

Therefore, the lowest common multiple of 280,334,138 is 3226440.

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.

280 x 334 x 138 = 12905760

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.

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

334 : 1, 2, 167, 334

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,334,138, is 2.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

334:2x 167

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 12905760/(2x2)

LCM = 12905760/4

LCM = 3226440

Thus, we can understand that the LCM of 280,334,138 is 3226440.

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