Given numbers are 689, 777, 247, 943
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 777) = 535353
GCD(689, 777) = ( 689 x 777 ) / 535353
= 689 / 777
= 689
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
So, Greatest Common Divisor of 689, 777, 247, 943 is 1
