GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(769, 225) = 173025
GCD(769, 225) = ( 769 x 225 ) / 173025
= 769 / 225
= 769
Step2:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 769, 225, 798, 489 is 1
