Given numbers are 771, 308, 741, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 308) = 237468
GCD(771, 308) = ( 771 x 308 ) / 237468
= 771 / 308
= 771
Step2:
LCM(1, 741) = 741
GCD(1, 741) = ( 1 x 741 ) / 741
= 1 / 741
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 771, 308, 741, 691 is 1
