Given numbers are 181, 851, 981, 165

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

Apply this formula for all numbers.

Step1:

LCM(181, 851) = 154031

GCD(181, 851) = ( 181 x 851 ) / 154031

= 181 / 851

= 181

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 181, 851, 981, 165 is 1
