GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 814) = 212454
GCD(261, 814) = ( 261 x 814 ) / 212454
= 261 / 814
= 261
Step2:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 261, 814, 683, 680 is 1
