Was there a different method of counting of age at the time of events of Old Testament? (Catholic perspective)

Genesis 5:6-32(RSVCE) gives an account of the generations of Adam. Prima facie, eldest sons were born to the forefathers when some of them had completed or were about to complete a hundred years of age! For instance, Genesis says: When Seth had lived a hundred and five years, he became the father of Enosh. When Enosh had lived ninety years, he became the father of Kenan. When Lamech had lived a hundred and eighty-two years, he became the father of a son, and called his name Noah. After Noah was five hundred years old, Noah became the father of Shem, Ham, and Japheth. All that puts one is serious doubt whether there was a different method of counting of age, during the ancient times. My question is: has the Catholic Church made any studies into the system of counting of age that was prevalent at the time of events of the OT?
