Given numbers are 561, 368, 721, 124

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

Apply this formula for all numbers.

Step1:

LCM(561, 368) = 206448

GCD(561, 368) = ( 561 x 368 ) / 206448

= 561 / 368

= 561

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 561, 368, 721, 124 is 1
