GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 836) = 17556
GCD(399, 836) = ( 399 x 836 ) / 17556
= 399 / 836
= 399
Step2:
LCM(19, 977) = 18563
GCD(19, 977) = ( 19 x 977 ) / 18563
= 19 / 977
= 19
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 399, 836, 977, 691 is 1
