Given numbers are 561, 225, 639, 574

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

Apply this formula for all numbers.

Step1:

LCM(561, 225) = 42075

GCD(561, 225) = ( 561 x 225 ) / 42075

= 561 / 225

= 561

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 574) = 1722

GCD(3, 574) = ( 3 x 574 ) / 1722

= 3 / 574

= 3

So, Greatest Common Divisor of 561, 225, 639, 574 is 1
