Given numbers are 644, 184, 747, 196

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

Apply this formula for all numbers.

Step1:

LCM(644, 184) = 1288

GCD(644, 184) = ( 644 x 184 ) / 1288

= 644 / 184

= 644

Step2:

LCM(92, 747) = 68724

GCD(92, 747) = ( 92 x 747 ) / 68724

= 92 / 747

= 92

Step3:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

So, Greatest Common Divisor of 644, 184, 747, 196 is 1
