Given numbers are 684, 988, 766, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 988) = 8892
GCD(684, 988) = ( 684 x 988 ) / 8892
= 684 / 988
= 684
Step2:
LCM(76, 766) = 29108
GCD(76, 766) = ( 76 x 766 ) / 29108
= 76 / 766
= 76
Step3:
LCM(2, 561) = 1122
GCD(2, 561) = ( 2 x 561 ) / 1122
= 2 / 561
= 2
So, Greatest Common Divisor of 684, 988, 766, 561 is 1
