Given numbers are 265, 770, 455, 430

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

Apply this formula for all numbers.

Step1:

LCM(265, 770) = 40810

GCD(265, 770) = ( 265 x 770 ) / 40810

= 265 / 770

= 265

Step2:

LCM(5, 455) = 455

GCD(5, 455) = ( 5 x 455 ) / 455

= 5 / 455

= 5

Step3:

LCM(5, 430) = 430

GCD(5, 430) = ( 5 x 430 ) / 430

= 5 / 430

= 5

So, Greatest Common Divisor of 265, 770, 455, 430 is 5
