Given numbers are 286, 778, 130, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(286, 778) = 111254
GCD(286, 778) = ( 286 x 778 ) / 111254
= 286 / 778
= 286
Step2:
LCM(2, 130) = 130
GCD(2, 130) = ( 2 x 130 ) / 130
= 2 / 130
= 2
Step3:
LCM(2, 211) = 422
GCD(2, 211) = ( 2 x 211 ) / 422
= 2 / 211
= 2
So, Greatest Common Divisor of 286, 778, 130, 211 is 1
