Given numbers are 711, 642, 449, 203

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

Apply this formula for all numbers.

Step1:

LCM(711, 642) = 152154

GCD(711, 642) = ( 711 x 642 ) / 152154

= 711 / 642

= 711

Step2:

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

= 3 / 449

= 3

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 711, 642, 449, 203 is 1
