Given numbers are 687, 460, 791, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 460) = 316020
GCD(687, 460) = ( 687 x 460 ) / 316020
= 687 / 460
= 687
Step2:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
Step3:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
So, Greatest Common Divisor of 687, 460, 791, 430 is 1
