Given numbers are 203,689,221,227

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

The LCM of 203,689,221,227 is 539746753.

Find LCM of 203,689,221,227 with Prime Factorization

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

13 x 203 x 53 x 17 x 227 = 539746753

Therefore, the lowest common multiple of 203,689,221,227 is 539746753.

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.

203 x 689 x 221 x 227 = 7016707789

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.

203 : 1, 7, 29, 203

689 : 1, 13, 53, 689

221 : 1, 13, 17, 221

227 : 1, 227

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,689,221,227, is 1.

Now, the common factors can be found like this.

203:7x 29

689:13x 53

221:13x 17

227:227

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

13 = 13

Therefore, the value for common factors is 13.

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 = 7016707789/(1x13)

LCM = 7016707789/13

LCM = 539746753

Thus, we can understand that the LCM of 203,689,221,227 is 539746753.
