Given numbers are 809, 980, 518, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 980) = 792820
GCD(809, 980) = ( 809 x 980 ) / 792820
= 809 / 980
= 809
Step2:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 809, 980, 518, 211 is 1
