Given numbers are 196, 679, 656, 661

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

Apply this formula for all numbers.

Step1:

LCM(196, 679) = 19012

GCD(196, 679) = ( 196 x 679 ) / 19012

= 196 / 679

= 196

Step2:

LCM(7, 656) = 4592

GCD(7, 656) = ( 7 x 656 ) / 4592

= 7 / 656

= 7

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 196, 679, 656, 661 is 1
