Given numbers are 491, 791, 646, 893

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

Apply this formula for all numbers.

Step1:

LCM(491, 791) = 388381

GCD(491, 791) = ( 491 x 791 ) / 388381

= 491 / 791

= 491

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 893) = 893

GCD(1, 893) = ( 1 x 893 ) / 893

= 1 / 893

= 1

So, Greatest Common Divisor of 491, 791, 646, 893 is 1
