GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 440) = 91080
GCD(207, 440) = ( 207 x 440 ) / 91080
= 207 / 440
= 207
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 207, 440, 249, 957 is 1
