Given numbers are 557,438,146,227

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

The LCM of 557,438,146,227 is 55380282.

Find LCM of 557,438,146,227 with Prime Factorization

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

2 x 73 x 557 x 3 x 1 x 227 = 55380282

Therefore, the lowest common multiple of 557,438,146,227 is 55380282.

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.

557 x 438 x 146 x 227 = 8085521172

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.

557 : 1, 557

438 : 1, 2, 3, 6, 73, 146, 219, 438

146 : 1, 2, 73, 146

227 : 1, 227

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,438,146,227, is 1.

Now, the common factors can be found like this.

557:557

438:2x 3x 73

146:2x 73

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.

2x 73 = 146

Therefore, the value for common factors is 146.

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 = 8085521172/(1x146)

LCM = 8085521172/146

LCM = 55380282

Thus, we can understand that the LCM of 557,438,146,227 is 55380282.
