Given numbers are 622, 771, 551, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(622, 771) = 479562
GCD(622, 771) = ( 622 x 771 ) / 479562
= 622 / 771
= 622
Step2:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 622, 771, 551, 390 is 1
