Answer:
10
Step-by-step explanation:
the GCF of both 50 and 40 is to because you can add 10 and get to 50 and 40
Answer:
10
Step-by-step explanation:
The greatest common factor (GCF) of 40 = 10×4 and 50 = 10×5 is 10.
_____
The GCF can be no larger than the difference of the two numbers. If that difference divides the smaller number evenly, it is the GCF.
50 - 40 = 10
40/10 = 4 remainder 0, so 10 is the GCF
__
Actually, the algorithm is to compute the value of the remainder of the larger number divided by the smaller. Here, the larger number is less than twice the smaller, so that remainder is the difference of the two numbers. If the remainder is zero, the smaller number is the GCF. If it is not, then the GCF is the GCF of the remainder and the smaller number. (It's a recursive algorithm.)
For this problem, this looks like ...
50 mod 40 = 10
40 mod 10 = 0, so 10 is the GCF
