Conversation between a priest and an organist in a church

The priest told the organist'Today there were 3 persons in the church besides us.The product of their ages was 2450 and the sum equal to twice your age.How old were they?' The organist who was clever,thought for a while and said'No,I cant figure that out'.The priest replied'If I tell you that I was the oldest person in the church today,can you solve the problem?'.The organist was able to do that.
Now comes a question for you-How old was the priest?
