The GCF of 54 and 84 is 6.step 1: list all of the prime numbers that go into 54 and 84.2*3*3*3=542*2*3*7=84step 2: find the common prime numbers between both sets.2*3*3*3=542*2*3*7=842*3step 3: multiply your answer.2*3=66 is the greatest common factor
The GCF of 35, 63, and 84 is 7. The prime factorization of 35 is 5*7. The prime factorization of 63 is 3*3*7 The prime factorization of 84 is 2*2*3*7 The GCF of 35, 63, and 84 is thus 7.
The largest prime factor is 7.
The greatest common factor of 49 and 84 is 7
2 x 2 x 3 x 7 makes it composite.
7 is the greatest prime factor of 84.
To find the prime factors of a number, divide the number by each prime number up to the greatest prime that will go into the number leaving no remainder. This is the process for factorization of 168: 168/2=84 84/2=42 42/2=21 21/3=7 7/7=1 Listing each divisor as a prime factor, the prime factors of 324 iare 2x2x2x3x7.
The greatest common factor of 54, 57, and 84 is 1, because 57 is a prime number, which means it can only be divided by 1 and itself. The greatest common factor of 54 and 84 is 6.

There are only 9 numbers between 80 and 90 - so lets look at them all Remember we only need to find 1 number that will divide the number except for 1 and itself for it to be NON-PRIME. 81 - 3 will of course divide this number - so not prime. 82 - 2 will of course divide this number - so not prime. 83 - PRIME!!! 84 - 3 will of course divide this number - so not prime. 85 - 5 will of course divide this number - so not prime. 86 - 2 will of course divide this number - so not prime. 87 - 3 will of course divide this number - so not prime. 88 - 2 will of course divide this number - so not prime. 89 - PRIME!!! So, the only numbers between 80 and 90 that are primes are 83 and 89!
84/15=5.6 5.6 is not an integer, so it can't be prime or composite.
The greatest factor of any number is itself.
Prime :)
Neither number is prime: 117 is divisible by 3 and 84 is divisible by 2.
No prime numbers equal 84. The only number equal to 84 is 84,and it isn't a prime number.The prime factors of 84 are: 1, 2, 2, 3, and 7
84 is a composite number. as it is divisible by 1,2,3.. etc.
