Use euclid division algorithm to find the HCF of 135 and 225

Posted by Neha Gujjar 5 years, 7 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 5 years, 7 months ago

Here 225 > 135 we always divide greater number with smaller one.
Divide 225 by 135 we get 1 quotient and 90 as remainder so that
225= 135× 1 + 90
Divide 135 by 90 we get 1 quotient and 45 as remainder so that
135= 90× 1 + 45
Divide 90 by 45 we get 2 quotient and no remainder so we can write it as
90 = 2× 45+ 0
As there are no remainder so deviser 45 is our HCF
