Tips & Tricks Given: Number of oranges = 540 Number of apples = 450 Number of bananas = 630 Concept used: Always take HCF whenever we have to find the maximum number of the product. Calculations: Taking the HCF of the number of oranges, apples and bananas 540=22×33×5 450=2×32×52 630=2×32×5×7 HCF =2×32×5=90 So, maximum number of devotes = 90 ∴ The maximum number of devotes is 90
