Given numbers are 561,247,283,455

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

The LCM of 561,247,283,455 is 1372506135.

Find LCM of 561,247,283,455 with Prime Factorization

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

13 x 561 x 19 x 283 x 35 = 1372506135

Therefore, the lowest common multiple of 561,247,283,455 is 1372506135.

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.

561 x 247 x 283 x 455 = 17842579755

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

247 : 1, 13, 19, 247

283 : 1, 283

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,247,283,455, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

247:13x 19

283:283

455:5x 7x 13

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 = 17842579755/(1x13)

LCM = 17842579755/13

LCM = 1372506135

Thus, we can understand that the LCM of 561,247,283,455 is 1372506135.
