Given numbers are 687, 450, 957, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 450) = 103050
GCD(687, 450) = ( 687 x 450 ) / 103050
= 687 / 450
= 687
Step2:
LCM(3, 957) = 957
GCD(3, 957) = ( 3 x 957 ) / 957
= 3 / 957
= 3
Step3:
LCM(3, 211) = 633
GCD(3, 211) = ( 3 x 211 ) / 633
= 3 / 211
= 3
So, Greatest Common Divisor of 687, 450, 957, 211 is 1
