The numbers are: 76 and 20
Amongst others they can be 2+3+15 = 20 which is a multiple of 10
116
the answer is yes Example: -20 +20=0
28
10 and 20, among others. -- Pick any multiple of 10. -- Add 10 to it. -- There you have two numbers whose GCF is 10.
A single number, 20, does not have a lowest common multiple! So there are no two numbers to go in.
If the two numbers are relatively prime, their least common multiple is their product. The prime factors of 99 are 3, 3, and 11. Since the two numbers are relatively prime, the possibilities are 9 and 11 or 1 and 99. The pair of 9 and 11 add up to 20 and their least common multiple is 99. So, 9 and 11 are the two numbers.
20 + 19 = 39The two consecutive numbers that add up to 39 are 19 and 20.
20 and 3
The numbers are: -1 and -20
The numbers are: 76 and 20
Amongst others they can be 2+3+15 = 20 which is a multiple of 10
10 and 20, among others.
They are 3+17 = 20
"common" requires at least two numbers...
3 and 20
