Given numbers are 514, 469, 790, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(514, 469) = 241066
GCD(514, 469) = ( 514 x 469 ) / 241066
= 514 / 469
= 514
Step2:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 514, 469, 790, 420 is 1
