Given numbers are 206, 687, 438, 265

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

Apply this formula for all numbers.

Step1:

LCM(206, 687) = 141522

GCD(206, 687) = ( 206 x 687 ) / 141522

= 206 / 687

= 206

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

So, Greatest Common Divisor of 206, 687, 438, 265 is 1
