Given numbers are 669, 561, 25, 252

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

Apply this formula for all numbers.

Step1:

LCM(669, 561) = 125103

GCD(669, 561) = ( 669 x 561 ) / 125103

= 669 / 561

= 669

Step2:

LCM(3, 25) = 75

GCD(3, 25) = ( 3 x 25 ) / 75

= 3 / 25

= 3

Step3:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

So, Greatest Common Divisor of 669, 561, 25, 252 is 1
