Given numbers are 783, 885, 641, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 885) = 230985
GCD(783, 885) = ( 783 x 885 ) / 230985
= 783 / 885
= 783
Step2:
LCM(3, 641) = 1923
GCD(3, 641) = ( 3 x 641 ) / 1923
= 3 / 641
= 3
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 783, 885, 641, 385 is 1
