Given numbers are 121,174,223,407

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

The LCM of 121,174,223,407 is 173716554.

Find LCM of 121,174,223,407 with Prime Factorization

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

11 x 11 x 174 x 223 x 37 = 173716554

Therefore, the lowest common multiple of 121,174,223,407 is 173716554.

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.

121 x 174 x 223 x 407 = 1910882094

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.

121 : 1, 11, 121

174 : 1, 2, 3, 6, 29, 58, 87, 174

223 : 1, 223

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,174,223,407, is 1.

Now, the common factors can be found like this.

121:11x 11

174:2x 3x 29

223:223

407:11x 37

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

11 = 11

Therefore, the value for common factors is 11.

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 = 1910882094/(1x11)

LCM = 1910882094/11

LCM = 173716554

Thus, we can understand that the LCM of 121,174,223,407 is 173716554.
