Given numbers are 255,10,646

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

The LCM of 255,10,646 is 9690.

Find LCM of 255,10,646 with Prime Factorization

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

2 x 5 x 17 x 3 x 1 x 19 = 9690

Therefore, the lowest common multiple of 255,10,646 is 9690.

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.

255 x 10 x 646 = 1647300

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.

255 : 1, 3, 5, 15, 17, 51, 85, 255

10 : 1, 2, 5, 10

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,10,646, is 1.

Now, the common factors can be found like this.

255:3x 5x 17

10:2x 5

646:2x 17x 19

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

2x 5x 17 = 170

Therefore, the value for common factors is 170.

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 = 1647300/(1x170)

LCM = 1647300/170

LCM = 9690

Thus, we can understand that the LCM of 255,10,646 is 9690.

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

• LCM of 498, 66, 510
