GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 497) = 425929
GCD(857, 497) = ( 857 x 497 ) / 425929
= 857 / 497
= 857
Step2:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 857, 497, 964, 645 is 1
