GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 139) = 96049
GCD(691, 139) = ( 691 x 139 ) / 96049
= 691 / 139
= 691
Step2:
LCM(1, 359) = 359
GCD(1, 359) = ( 1 x 359 ) / 359
= 1 / 359
= 1
Step3:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
So, Greatest Common Divisor of 691, 139, 359, 511 is 1
