Given numbers are 656, 864, 178, 487

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

Apply this formula for all numbers.

Step1:

LCM(656, 864) = 35424

GCD(656, 864) = ( 656 x 864 ) / 35424

= 656 / 864

= 656

Step2:

LCM(16, 178) = 1424

GCD(16, 178) = ( 16 x 178 ) / 1424

= 16 / 178

= 16

Step3:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

So, Greatest Common Divisor of 656, 864, 178, 487 is 1
