Given numbers are 561, 917, 497, 549

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

Apply this formula for all numbers.

Step1:

LCM(561, 917) = 514437

GCD(561, 917) = ( 561 x 917 ) / 514437

= 561 / 917

= 561

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 561, 917, 497, 549 is 1
