Question

find the HCF of 405and2520​

Answer 1

Answer:

405 and 2520

Step-by-step explanation:

HCF = 45 is right

Answer 2

Answer:

the HCF of 2520 and 405 is 45

Step-by-step explanation:

On applying Euclid’s algorithm,

dividing 2520 by 405

we get:  Quotient = 6, Remainder = 90  

∴ 2520 = 405 × 6 + 90  

then,

on applying Euclid’s algorithm,

dividing 405 by 90

we get:  Quotient = 4, Remainder =  45

∴ 405 = 90 × 4 + 45  

then on applying Euclid’s algorithm,

dividing 90 by 45

we get:  ∴ 90 = 45 × 2 + 0

Hence, the HCF of 2520 and 405 is 45.
