Given numbers are 551, 210, 668, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 210) = 115710
GCD(551, 210) = ( 551 x 210 ) / 115710
= 551 / 210
= 551
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 551, 210, 668, 611 is 1
