42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
The least common denominator for 7, 8, and 10 is 280. Using the exponential method: 7 = 71 8 = 2 x 2 x 2 = 23 10 = 21 x 51 and the product of the largest exponential of each prime is 23 x 51 x 71 = 8 x 5 x 7 = 280
The common factor is 3. (105 = 35 x 3, 12 = 4 x 3).The least common denominator is 420.105 = 3 x 5 x 712 = 22 x 3Highest exponents method: 22 x 31 x 51 x 71 = 420

As the numerator and denominator don't have any common factors then the fraction is in its simplest form. If they weren't relatively prime then there would be a common factor and therefore the fraction could be simplified.

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 60 and 71 is 4260.
71 is a prime number, so its only factors are 1 and 71. Unless n is a multiple of 71, the greatest common factor is 1. If n is a multiple of 71, the greatest common factor is 71.
The common factor of 63 and 71 is and 1.
