Given numbers are 215,217,683,279

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

The LCM of 215,217,683,279 is 286788285.

Find LCM of 215,217,683,279 with Prime Factorization

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

31 x 215 x 7 x 683 x 9 = 286788285

Therefore, the lowest common multiple of 215,217,683,279 is 286788285.

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.

215 x 217 x 683 x 279 = 8890436835

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.

215 : 1, 5, 43, 215

217 : 1, 7, 31, 217

683 : 1, 683

279 : 1, 3, 9, 31, 93, 279

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,217,683,279, is 1.

Now, the common factors can be found like this.

215:5x 43

217:7x 31

683:683

279:3x 3x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 8890436835/(1x31)

LCM = 8890436835/31

LCM = 286788285

Thus, we can understand that the LCM of 215,217,683,279 is 286788285.
