Given numbers are 455, 775, 710, 280

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

Apply this formula for all numbers.

Step1:

LCM(455, 775) = 70525

GCD(455, 775) = ( 455 x 775 ) / 70525

= 455 / 775

= 455

Step2:

LCM(5, 710) = 710

GCD(5, 710) = ( 5 x 710 ) / 710

= 5 / 710

= 5

Step3:

LCM(5, 280) = 280

GCD(5, 280) = ( 5 x 280 ) / 280

= 5 / 280

= 5

So, Greatest Common Divisor of 455, 775, 710, 280 is 5
