Given numbers are 189, 957, 780, 262

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

Apply this formula for all numbers.

Step1:

LCM(189, 957) = 60291

GCD(189, 957) = ( 189 x 957 ) / 60291

= 189 / 957

= 189

Step2:

LCM(3, 780) = 780

GCD(3, 780) = ( 3 x 780 ) / 780

= 3 / 780

= 3

Step3:

LCM(3, 262) = 786

GCD(3, 262) = ( 3 x 262 ) / 786

= 3 / 262

= 3

So, Greatest Common Divisor of 189, 957, 780, 262 is 1
