Given numbers are 265, 505, 687, 161

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

Apply this formula for all numbers.

Step1:

LCM(265, 505) = 26765

GCD(265, 505) = ( 265 x 505 ) / 26765

= 265 / 505

= 265

Step2:

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

= 5 / 687

= 5

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 265, 505, 687, 161 is 1
