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
