GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 960) = 41280
GCD(688, 960) = ( 688 x 960 ) / 41280
= 688 / 960
= 688
Step2:
LCM(16, 261) = 4176
GCD(16, 261) = ( 16 x 261 ) / 4176
= 16 / 261
= 16
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 688, 960, 261, 979 is 1
