Given numbers are 491, 503, 457, 278

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

Apply this formula for all numbers.

Step1:

LCM(491, 503) = 246973

GCD(491, 503) = ( 491 x 503 ) / 246973

= 491 / 503

= 491

Step2:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 491, 503, 457, 278 is 1
