Given numbers are 780, 279, 353, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 279) = 72540
GCD(780, 279) = ( 780 x 279 ) / 72540
= 780 / 279
= 780
Step2:
LCM(3, 353) = 1059
GCD(3, 353) = ( 3 x 353 ) / 1059
= 3 / 353
= 3
Step3:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
So, Greatest Common Divisor of 780, 279, 353, 909 is 1
