Given numbers are 656, 456, 880, 189

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

Apply this formula for all numbers.

Step1:

LCM(656, 456) = 37392

GCD(656, 456) = ( 656 x 456 ) / 37392

= 656 / 456

= 656

Step2:

LCM(8, 880) = 880

GCD(8, 880) = ( 8 x 880 ) / 880

= 8 / 880

= 8

Step3:

LCM(8, 189) = 1512

GCD(8, 189) = ( 8 x 189 ) / 1512

= 8 / 189

= 8

So, Greatest Common Divisor of 656, 456, 880, 189 is 1
