Given numbers are 656, 399, 547, 158

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

Apply this formula for all numbers.

Step1:

LCM(656, 399) = 261744

GCD(656, 399) = ( 656 x 399 ) / 261744

= 656 / 399

= 656

Step2:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 656, 399, 547, 158 is 1
