Given numbers are 645, 832, 470, 677
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 832) = 536640
GCD(645, 832) = ( 645 x 832 ) / 536640
= 645 / 832
= 645
Step2:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
Step3:
LCM(1, 677) = 677
GCD(1, 677) = ( 1 x 677 ) / 677
= 1 / 677
= 1
So, Greatest Common Divisor of 645, 832, 470, 677 is 1
