Given numbers are 784, 126, 881, 243

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

Apply this formula for all numbers.

Step1:

LCM(784, 126) = 7056

GCD(784, 126) = ( 784 x 126 ) / 7056

= 784 / 126

= 784

Step2:

LCM(14, 881) = 12334

GCD(14, 881) = ( 14 x 881 ) / 12334

= 14 / 881

= 14

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 784, 126, 881, 243 is 1
