Given numbers are 355, 255, 981, 280

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

Apply this formula for all numbers.

Step1:

LCM(355, 255) = 18105

GCD(355, 255) = ( 355 x 255 ) / 18105

= 355 / 255

= 355

Step2:

LCM(5, 981) = 4905

GCD(5, 981) = ( 5 x 981 ) / 4905

= 5 / 981

= 5

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 355, 255, 981, 280 is 1
