Given numbers are 211,128,190,418

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

The LCM of 211,128,190,418 is 28223360.

Find LCM of 211,128,190,418 with Prime Factorization

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

2 x 19 x 211 x 64 x 5 x 11 = 28223360

Therefore, the lowest common multiple of 211,128,190,418 is 28223360.

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.

211 x 128 x 190 x 418 = 2144975360

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.

211 : 1, 211

128 : 1, 2, 4, 8, 16, 32, 64, 128

190 : 1, 2, 5, 10, 19, 38, 95, 190

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,128,190,418, is 1.

Now, the common factors can be found like this.

211:211

128:2x 2x 2x 2x 2x 2x 2

190:2x 5x 19

418:2x 11x 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 2x 19 = 76

Therefore, the value for common factors is 76.

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 = 2144975360/(1x76)

LCM = 2144975360/76

LCM = 28223360

Thus, we can understand that the LCM of 211,128,190,418 is 28223360.
