Given numbers are 790, 140, 771, 550
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 140) = 11060
GCD(790, 140) = ( 790 x 140 ) / 11060
= 790 / 140
= 790
Step2:
LCM(10, 771) = 7710
GCD(10, 771) = ( 10 x 771 ) / 7710
= 10 / 771
= 10
Step3:
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
= 1 / 550
= 1
So, Greatest Common Divisor of 790, 140, 771, 550 is 1
