Given :
Number of raspberry scones with Bryson = 51
Number of blueberry scones with Bryson = 34
To find the greatest number of bags Bryson can fill with equal number of raspberry and blueberry cones each, we need to find the GCF of the number of blueberry scones and raspberry scones.
Factors of 34 = 1, 2, 17, 34
Factors of 51 = 1, 3, 17, 51
Greatest common factor (GCF) of 34 and 51 = 17
Therefore, the greatest number of bags Bryson can fill with equal number of blueberry scones and raspberry scones = 17 bags
