Given numbers are 836, 851, 220, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(836, 851) = 711436
GCD(836, 851) = ( 836 x 851 ) / 711436
= 836 / 851
= 836
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 836, 851, 220, 397 is 1
