Given numbers are 165, 109, 274, 860

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

Apply this formula for all numbers.

Step1:

LCM(165, 109) = 17985

GCD(165, 109) = ( 165 x 109 ) / 17985

= 165 / 109

= 165

Step2:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 165, 109, 274, 860 is 1
