GCF(168, 180, 450) = 6.
The GCF is 6.
To find the greatest common factor (GCF) of 180, 450, and 420, we first need to find the prime factorization of each number. The prime factorization of 180 is 2^2 x 3^2 x 5, the prime factorization of 450 is 2 x 3^2 x 5^2, and the prime factorization of 420 is 2^2 x 3 x 5 x 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 x 3 = 12. Therefore, the greatest common factor of 180, 450, and 420 is 12.
The prime factorization of 450 is 2 x 3 x 3 x 5 x 5
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
No
For 168: 2, 3, 7 For 180: 2, 3, 5 For 450: 2, 3, 5
It is 90
2 x 2 x 2 x 3 x 7 = 168 2 x 2 x 3 x 3 x 5 = 180 2 x 3 x 3 x 5 x 5 = 450
A set of even numbers cannot be relatively prime. They are all divisible by 2.
2 x 2 x 2 x 3 x 7 = 168 2 x 2 x 3 x 3 x 5 = 180 2 x 3 x 3 x 5 x 5 = 450 2 x 3 = 6, the GCF
GCF(168, 180, 450) = 6.
GCF (168, 180, 450) = 6
450 = 2 × 32 × 52
