The greatest common factor of the numbers 180 and 150 is 30.
Since 210 is a factor of 420, it is automatically the GCF.
The GCF is 12.
The GCF is 35.
The GCF is 60.
The GCF is 12.
The GCF is 84.
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 greatest common factor (GCF) of 420, 616 and 2184 is 28.
The GCF is 30.
The GCF is 105.
The GCF is 20.
