Given numbers are 221,112,202,398

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

The LCM of 221,112,202,398 is 497490448.

Find LCM of 221,112,202,398 with Prime Factorization

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

2 x 221 x 56 x 101 x 199 = 497490448

Therefore, the lowest common multiple of 221,112,202,398 is 497490448.

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.

221 x 112 x 202 x 398 = 1989961792

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.

221 : 1, 13, 17, 221

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

202 : 1, 2, 101, 202

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,112,202,398, is 1.

Now, the common factors can be found like this.

221:13x 17

112:2x 2x 2x 2x 7

202:2x 101

398:2x 199

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 1989961792/(1x4)

LCM = 1989961792/4

LCM = 497490448

Thus, we can understand that the LCM of 221,112,202,398 is 497490448.
