Given numbers are 665, 781, 459, 437

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

Apply this formula for all numbers.

Step1:

LCM(665, 781) = 519365

GCD(665, 781) = ( 665 x 781 ) / 519365

= 665 / 781

= 665

Step2:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 665, 781, 459, 437 is 1
