Given numbers are 781, 921, 80, 803

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

Apply this formula for all numbers.

Step1:

LCM(781, 921) = 719301

GCD(781, 921) = ( 781 x 921 ) / 719301

= 781 / 921

= 781

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 781, 921, 80, 803 is 1
