Given numbers are 164, 574, 641, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 574) = 1148
GCD(164, 574) = ( 164 x 574 ) / 1148
= 164 / 574
= 164
Step2:
LCM(82, 641) = 52562
GCD(82, 641) = ( 82 x 641 ) / 52562
= 82 / 641
= 82
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 164, 574, 641, 691 is 1
