GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 357) = 196707
GCD(551, 357) = ( 551 x 357 ) / 196707
= 551 / 357
= 551
Step2:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 551, 357, 797, 280 is 1
