Given numbers are 281, 530, 223, 128

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

Apply this formula for all numbers.

Step1:

LCM(281, 530) = 148930

GCD(281, 530) = ( 281 x 530 ) / 148930

= 281 / 530

= 281

Step2:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 281, 530, 223, 128 is 1
