The HCF of 900 and 250 by using Euclid's division Algorithm
EVALUATION
Euclidean algorithm is an efficient method of finding the highest common factor of two given integers.
The method involves repeated application of the division algorithm
900 = ( 3 × 250 ) + 150
250 = ( 1 × 150 ) + 100
150 = ( 1 × 100 ) + 50
100 = ( 2 × 50 ) + 0
Thus we get
50
= 150 - ( 2 × 50 )
= 150 - 2 × ( 150 - 100 )
= 2 × 100 - 150
= 2 × ( 250 - 150 ) - 150
= 2 × 250 - 3 × 150
= 2 × 250 - 3 × [ 900 - ( 3 × 250 ) ]
= 11 × 250 - 3 × 900
∴ 11 × 250 - 3 × 900 = 50
Hence the required HCF = 50
