Given numbers are 786, 254, 256, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 254) = 99822
GCD(786, 254) = ( 786 x 254 ) / 99822
= 786 / 254
= 786
Step2:
LCM(2, 256) = 256
GCD(2, 256) = ( 2 x 256 ) / 256
= 2 / 256
= 2
Step3:
LCM(2, 197) = 394
GCD(2, 197) = ( 2 x 197 ) / 394
= 2 / 197
= 2
So, Greatest Common Divisor of 786, 254, 256, 197 is 1
