Given numbers are 281, 291, 813, 656

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

Apply this formula for all numbers.

Step1:

LCM(281, 291) = 81771

GCD(281, 291) = ( 281 x 291 ) / 81771

= 281 / 291

= 281

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 281, 291, 813, 656 is 1
