Given numbers are 1144,1661

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

The LCM of 1144,1661 is 172744.

Find LCM of 1144,1661 with Prime Factorization

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

11 x 104 x 151 = 172744

Therefore, the lowest common multiple of 1144,1661 is 172744.

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.

1144 x 1661 = 1900184

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.

1144 : 1, 2, 4, 8, 11, 13, 22, 26, 44, 52, 88, 104, 143, 286, 572, 1144

1661 : 1, 11, 151, 1661

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1144,1661, is 11.

Now, the common factors can be found like this.

1144:2x 2x 2x 11x 13

1661:11x 151

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 = 1900184/(11x1)

LCM = 1900184/11

LCM = 172744

Thus, we can understand that the LCM of 1144,1661 is 172744.
