20: 1,2,4,5,10,20
The cube root of -83 is -4.36207 (rounded). The number that is closest to this figure on that list that you have but refuse to share is the correct choice.
All multiples of 9 share common factors with 9.
Well, being that 7 is a prime number (only one and itself will go into it evenly), there are no other numbers that share all of the common factors of the number seven, and only those factors, but if you are asking what numbers share either or any of the common factors of seven, your answer would be, infinity. Because 1 will go into every other number except 0. I hope I'm understanding your question correctly.
As factors, 1, 2, 3 and 6.
27 and 37 don't share any prime factors.
the phi of n is the number of positive integers below n which do not share any factors with it. for example, the phi of 30 is 8 because it does not share any factors with 8 numbers: 1,7,11,13,17,19,23,29 these are called co-primes
Two numbers are considered to be co-prime if they share no common prime factors, that is, if their GCF is 1.
Humans share the closest DNA similarity with chimpanzees among all other species.
Norway share a long border with Sweden. And a short bit with Finland. Closest across water is Denmark.
99 and 512 are relatively prime. They don't share any prime factors.
Proper factors occur when you list all the factors of a number except for 1 and the number itself. Common factors occur when you compare a minimum of two sets of factors and see which ones they share.
