2018 NSW HSC Mathematics Extension 2 exam Q13

$Hardest maths questions - refactorisation and prime numbers Express 8×9×10×11×12×13×14 as another product of consecutive whole numbers. How can we factorise a number without calculating it? This question from the AMC junior division was answered correctly by 0% of students! To solve it, Ill show you how composite numbers can be pulled apart into their prime factors and recombined in new ways, which is a trick I use in a lot of different situations (mental arithmetic, finding an LCM when adding fractions or doing elimination, factorising quadratics, etc.).
