GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 533) = 208403
GCD(391, 533) = ( 391 x 533 ) / 208403
= 391 / 533
= 391
Step2:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 391, 533, 836, 957 is 1
