Given numbers are 231, 549, 965, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 549) = 42273
GCD(231, 549) = ( 231 x 549 ) / 42273
= 231 / 549
= 231
Step2:
LCM(3, 965) = 2895
GCD(3, 965) = ( 3 x 965 ) / 2895
= 3 / 965
= 3
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 231, 549, 965, 637 is 1
