Given numbers are 904,113,221,287

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

The LCM of 904,113,221,287 is 57338008.

Find LCM of 904,113,221,287 with Prime Factorization

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

113 x 8 x 1 x 221 x 287 = 57338008

Therefore, the lowest common multiple of 904,113,221,287 is 57338008.

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.

904 x 113 x 221 x 287 = 6479194904

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.

904 : 1, 2, 4, 8, 113, 226, 452, 904

113 : 1, 113

221 : 1, 13, 17, 221

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,113,221,287, is 1.

Now, the common factors can be found like this.

904:2x 2x 2x 113

113:113

221:13x 17

287:7x 41

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

113 = 113

Therefore, the value for common factors is 113.

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 = 6479194904/(1x113)

LCM = 6479194904/113

LCM = 57338008

Thus, we can understand that the LCM of 904,113,221,287 is 57338008.
