The GCF of 90 and 180 is 90.
No, their GCF is always odd.
prime
The GCF of 36, 54 and 73 is 1.
Very astute. The LCM and the GCF have an inverse relationship. Since their product equals the product of the original two numbers, the larger the GCF gets, the smaller the LCM is and vice versa.
There are infinitely many such pairs of numbers. As long as the only primes they have in common are 2×3²×5 (the prime factorization of 90) their gcf will be 90: Some examples: 90, 180 90, 270 90, 360 180, 270 180, 450 450, 630 630, 990
It is: 1
