Given numbers are 680, 465, 195, 265

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

Apply this formula for all numbers.

Step1:

LCM(680, 465) = 63240

GCD(680, 465) = ( 680 x 465 ) / 63240

= 680 / 465

= 680

Step2:

LCM(5, 195) = 195

GCD(5, 195) = ( 5 x 195 ) / 195

= 5 / 195

= 5

Step3:

LCM(5, 265) = 265

GCD(5, 265) = ( 5 x 265 ) / 265

= 5 / 265

= 5

So, Greatest Common Divisor of 680, 465, 195, 265 is 5
