Given numbers are 836, 203, 581, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(836, 203) = 169708
GCD(836, 203) = ( 836 x 203 ) / 169708
= 836 / 203
= 836
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 836, 203, 581, 420 is 1
