Given numbers are 691, 140, 357, 266
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 140) = 96740
GCD(691, 140) = ( 691 x 140 ) / 96740
= 691 / 140
= 691
Step2:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
Step3:
LCM(1, 266) = 266
GCD(1, 266) = ( 1 x 266 ) / 266
= 1 / 266
= 1
So, Greatest Common Divisor of 691, 140, 357, 266 is 1
