Given numbers are 851, 981, 658, 197

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

Apply this formula for all numbers.

Step1:

LCM(851, 981) = 834831

GCD(851, 981) = ( 851 x 981 ) / 834831

= 851 / 981

= 851

Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 851, 981, 658, 197 is 1
