Given numbers are 945, 891, 191, 505

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(945, 891) = 31185

GCD(945, 891) = ( 945 x 891 ) / 31185

= 945 / 891

= 945

Step2:

LCM(27, 191) = 5157

GCD(27, 191) = ( 27 x 191 ) / 5157

= 27 / 191

= 27

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 945, 891, 191, 505 is 1
