Given numbers are 644, 274, 934, 189

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

Apply this formula for all numbers.

Step1:

LCM(644, 274) = 88228

GCD(644, 274) = ( 644 x 274 ) / 88228

= 644 / 274

= 644

Step2:

LCM(2, 934) = 934

GCD(2, 934) = ( 2 x 934 ) / 934

= 2 / 934

= 2

Step3:

LCM(2, 189) = 378

GCD(2, 189) = ( 2 x 189 ) / 378

= 2 / 189

= 2

So, Greatest Common Divisor of 644, 274, 934, 189 is 1
