Given numbers are 891, 187, 957, 778

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

Apply this formula for all numbers.

Step1:

LCM(891, 187) = 15147

GCD(891, 187) = ( 891 x 187 ) / 15147

= 891 / 187

= 891

Step2:

LCM(11, 957) = 957

GCD(11, 957) = ( 11 x 957 ) / 957

= 11 / 957

= 11

Step3:

LCM(11, 778) = 8558

GCD(11, 778) = ( 11 x 778 ) / 8558

= 11 / 778

= 11

So, Greatest Common Divisor of 891, 187, 957, 778 is 1
