Given numbers are 481,247,420,227

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

The LCM of 481,247,420,227 is 871312260.

Find LCM of 481,247,420,227 with Prime Factorization

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

13 x 37 x 19 x 420 x 227 = 871312260

Therefore, the lowest common multiple of 481,247,420,227 is 871312260.

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.

481 x 247 x 420 x 227 = 11327059380

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.

481 : 1, 13, 37, 481

247 : 1, 13, 19, 247

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

227 : 1, 227

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,247,420,227, is 1.

Now, the common factors can be found like this.

481:13x 37

247:13x 19

420:2x 2x 3x 5x 7

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 = 11327059380/(1x13)

LCM = 11327059380/13

LCM = 871312260

Thus, we can understand that the LCM of 481,247,420,227 is 871312260.
