There is an infinite number of common multiples for 84 and 105. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
121 - 16 = 105. There are two other pairs.
A prime number is an integer which is greater than one and which is evenly divisible only by one and itself. A pair of prime numbers consists of two such numbers.
One possible pair is 1 and 105.
Suppose x and y are any two co-prime integers. Then 105*x and 105*y will have a GCF of 105.
The number is two.
The two numbers are coprime so the only number that goes into them evenly is 1.
No, fifteen is an odd number. It is not evenly divisible by two. Fifteen divided by two is seven and a half. All even numbers divide evenly by two.
The answer is 73.
The number two.
