The GCF of 15 and 77 is 1. The factors of 15 are 1, 3, 5, and 15. The factors of 77 are 1, 7, 11, and 77. The common factors are 1. Therefore the greatest common factor is 1, which means the two numbers are relatively prime. The greatest common factor can also be determined by prime factors. The prime factors of 15 are 3 and 5. The prime factors of 77 are 7 and 11. There are no common prime factors, so the two numbers are relatively prime, which means their only common factor is 1.
The numbers 7 and 11 divide into 77 evenly. We know that 7 x 11 = 77, and as 7 and 11 are both prime numbers, there are no other numbers that go into 77 evenly.
The least common multiple (LCM) of two numbers is the smallest multiple that is divisible by both numbers. In this case, the LCM of 7 and 11 is simply the product of the two numbers since they are prime numbers and have no common factors other than 1. Therefore, the LCM of 7 and 11 is 7 x 11 = 77.
Well, isn't that a happy little math problem we have here! Let's see, the two prime numbers that add up to 78 are 41 and 37. Just like in painting, sometimes you need to mix different colors to create something beautiful. Happy calculating!
