Given numbers are 283,573,247,221

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

The LCM of 283,573,247,221 is 680905641.

Find LCM of 283,573,247,221 with Prime Factorization

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

13 x 283 x 573 x 19 x 17 = 680905641

Therefore, the lowest common multiple of 283,573,247,221 is 680905641.

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.

283 x 573 x 247 x 221 = 8851773333

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.

283 : 1, 283

573 : 1, 3, 191, 573

247 : 1, 13, 19, 247

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 283,573,247,221, is 1.

Now, the common factors can be found like this.

283:283

573:3x 191

247:13x 19

221:13x 17

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 = 8851773333/(1x13)

LCM = 8851773333/13

LCM = 680905641

Thus, we can understand that the LCM of 283,573,247,221 is 680905641.
