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.
