Given numbers are 158, 318, 656, 641

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

Apply this formula for all numbers.

Step1:

LCM(158, 318) = 25122

GCD(158, 318) = ( 158 x 318 ) / 25122

= 158 / 318

= 158

Step2:

LCM(2, 656) = 656

GCD(2, 656) = ( 2 x 656 ) / 656

= 2 / 656

= 2

Step3:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

So, Greatest Common Divisor of 158, 318, 656, 641 is 1
