Given numbers are 430, 260, 742, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 260) = 11180
GCD(430, 260) = ( 430 x 260 ) / 11180
= 430 / 260
= 430
Step2:
LCM(10, 742) = 3710
GCD(10, 742) = ( 10 x 742 ) / 3710
= 10 / 742
= 10
Step3:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
So, Greatest Common Divisor of 430, 260, 742, 403 is 1
