Given numbers are 118,211,164,221

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

The LCM of 118,211,164,221 is 451201556.

Find LCM of 118,211,164,221 with Prime Factorization

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

2 x 59 x 211 x 82 x 221 = 451201556

Therefore, the lowest common multiple of 118,211,164,221 is 451201556.

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.

118 x 211 x 164 x 221 = 902403112

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.

118 : 1, 2, 59, 118

211 : 1, 211

164 : 1, 2, 4, 41, 82, 164

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,211,164,221, is 1.

Now, the common factors can be found like this.

118:2x 59

211:211

164:2x 2x 41

221:13x 17

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 = 902403112/(1x2)

LCM = 902403112/2

LCM = 451201556

Thus, we can understand that the LCM of 118,211,164,221 is 451201556.
