Given numbers are 680, 545, 988, 196
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 545) = 74120
GCD(680, 545) = ( 680 x 545 ) / 74120
= 680 / 545
= 680
Step2:
LCM(5, 988) = 4940
GCD(5, 988) = ( 5 x 988 ) / 4940
= 5 / 988
= 5
Step3:
LCM(1, 196) = 196
GCD(1, 196) = ( 1 x 196 ) / 196
= 1 / 196
= 1
So, Greatest Common Divisor of 680, 545, 988, 196 is 1
