Given numbers are 551, 290, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 290) = 5510
GCD(551, 290) = ( 551 x 290 ) / 5510
= 551 / 290
= 551
Step2:
LCM(29, 680) = 19720
GCD(29, 680) = ( 29 x 680 ) / 19720
= 29 / 680
= 29
So, Greatest Common Divisor of 551, 290, 680 is 1
