i think it is 10 times 11 but it said it was wrong for me on hegarty maths

The products of the primes are the composites.

102 = 2*3*17

The prime factors of 70 are 2,5 and 7 so their product is 70. This will happen whenever the prime factors occur only once. When we factor 70 into primes, we are asking for those primes who product is equal to 70. However, sometimes we get one or more primes raise to a power in the prime factorization. In this case, the prime raised to a power is no longer a prime so the product of prime factors is less than the number.
