Given numbers are 247, 178, 656, 381

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

Apply this formula for all numbers.

Step1:

LCM(247, 178) = 43966

GCD(247, 178) = ( 247 x 178 ) / 43966

= 247 / 178

= 247

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 247, 178, 656, 381 is 1
