Given numbers are 781, 545, 437, 454

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

Apply this formula for all numbers.

Step1:

LCM(781, 545) = 425645

GCD(781, 545) = ( 781 x 545 ) / 425645

= 781 / 545

= 781

Step2:

LCM(1, 437) = 437

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

= 1 / 437

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 781, 545, 437, 454 is 1
