Given numbers are 3171,1221

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

The LCM of 3171,1221 is 1290597.

Find LCM of 3171,1221 with Prime Factorization

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

3 x 1057 x 407 = 1290597

Therefore, the lowest common multiple of 3171,1221 is 1290597.

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.

3171 x 1221 = 3871791

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.

3171 : 1, 3, 7, 21, 151, 453, 1057, 3171

1221 : 1, 3, 11, 33, 37, 111, 407, 1221

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3171,1221, is 3.

Now, the common factors can be found like this.

3171:3x 7x 151

1221:3x 11x 37

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

= 1

Therefore, the value for common factors is 1.

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 = 3871791/(3x1)

LCM = 3871791/3

LCM = 1290597

Thus, we can understand that the LCM of 3171,1221 is 1290597.
