Maths - Factors of the 1960's

Some children in the Later Years Primary have been investigating the factors of the 1960's using their knowledge of divisibility tests and division skills.

They were set the following question:

What numbers go exactly (with no remainders) into the following years/numbers
1960, 1961, 1962, 1963, 1964, 1965, 1966, 1967, 1968, 1969?

Some of the factors found for 1960 were: 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 49, 56, 70, 98, 140, 196, 245, 280, 392, 490, 980, 1960

The children were then asked to use their maths skills to work out which of the years in the sixties were leap years.
