Given : Bryan is making balloon Arrangements he has 8 blue and 12 cream balloons.
Then , to find the greatest amount of Arrangements he can make if he wants them to be identical we need to find the greatest common factor (G.C.F.) of 8 and 12.
Prime factorization of 8 and 12:-
GCF of 8 and 12 =
Hence, the greatest amount of Arrangements he can make if he wants them to be identical = 4.
