Given numbers are 217, 787, 277, 441

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

Apply this formula for all numbers.

Step1:

LCM(217, 787) = 170779

GCD(217, 787) = ( 217 x 787 ) / 170779

= 217 / 787

= 217

Step2:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

Step3:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

So, Greatest Common Divisor of 217, 787, 277, 441 is 1
