Given numbers are 687, 831, 385, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 831) = 190299
GCD(687, 831) = ( 687 x 831 ) / 190299
= 687 / 831
= 687
Step2:
LCM(3, 385) = 1155
GCD(3, 385) = ( 3 x 385 ) / 1155
= 3 / 385
= 3
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 687, 831, 385, 441 is 1
