Given numbers are 290,52,391

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

The LCM of 290,52,391 is 2948140.

Find LCM of 290,52,391 with Prime Factorization

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

2 x 145 x 26 x 391 = 2948140

Therefore, the lowest common multiple of 290,52,391 is 2948140.

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.

290 x 52 x 391 = 5896280

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

52 : 1, 2, 4, 13, 26, 52

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,52,391, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

52:2x 2x 13

391:17x 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 = 5896280/(1x2)

LCM = 5896280/2

LCM = 2948140

Thus, we can understand that the LCM of 290,52,391 is 2948140.

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

• LCM of 502, 11, 857
• LCM of 239, 36, 274
