Given numbers are 288, 388, 872, 661

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

Apply this formula for all numbers.

Step1:

LCM(288, 388) = 27936

GCD(288, 388) = ( 288 x 388 ) / 27936

= 288 / 388

= 288

Step2:

LCM(4, 872) = 872

GCD(4, 872) = ( 4 x 872 ) / 872

= 4 / 872

= 4

Step3:

LCM(4, 661) = 2644

GCD(4, 661) = ( 4 x 661 ) / 2644

= 4 / 661

= 4

So, Greatest Common Divisor of 288, 388, 872, 661 is 1
