Given numbers are 561, 498, 256, 127

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

Apply this formula for all numbers.

Step1:

LCM(561, 498) = 93126

GCD(561, 498) = ( 561 x 498 ) / 93126

= 561 / 498

= 561

Step2:

LCM(3, 256) = 768

GCD(3, 256) = ( 3 x 256 ) / 768

= 3 / 256

= 3

Step3:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

So, Greatest Common Divisor of 561, 498, 256, 127 is 1
