Given numbers are 644, 994, 463, 187

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

Apply this formula for all numbers.

Step1:

LCM(644, 994) = 45724

GCD(644, 994) = ( 644 x 994 ) / 45724

= 644 / 994

= 644

Step2:

LCM(14, 463) = 6482

GCD(14, 463) = ( 14 x 463 ) / 6482

= 14 / 463

= 14

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 644, 994, 463, 187 is 1
