Given numbers are 680, 311, 128, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 311) = 211480
GCD(680, 311) = ( 680 x 311 ) / 211480
= 680 / 311
= 680
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 680, 311, 128, 656 is 1
