54 and 72 are divisible by 2,3.
67 and 5
The prime factors of 72 are: 2 and 3.
No, 72 and 252 are not relatively prime. No pair of even numbers can be relatively prime.
Only 1 because 72 is a prime number which is a whole number greater than on two factors
73 is prime.
2*72 = 98Surely a squared number is not a prime number?Another answer:19+79 = 98
144 is the answer to 122 so can be easily prime factorized as 2x2x2x2x3x3 72 is 9x8, so can be prime factorized as 2x2x2x3x3 These two numbers, therefore, have in common prime factors of 2, 2, 2, 3 and 3. Their greatest common factor is 72.
When the two numbers are coprime. Coprime numbers need not be prime numbers - they must not have any factor in common (other than 1). So, for eaxmple, neither 8 nor 9 are prime numbers but they are coprime and so, LCM(8 , 9) = 72
Negative numbers don't have prime factorizations.
There are two prime factors of 72: 2 and 3.
2 and 3: 72 = 2 x 2 x 2 x 3 x 3
