GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 840) = 78120
GCD(279, 840) = ( 279 x 840 ) / 78120
= 279 / 840
= 279
Step2:
LCM(3, 991) = 2973
GCD(3, 991) = ( 3 x 991 ) / 2973
= 3 / 991
= 3
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 279, 840, 991, 836 is 1
