Given numbers are 491, 620, 764, 785

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

Apply this formula for all numbers.

Step1:

LCM(491, 620) = 304420

GCD(491, 620) = ( 491 x 620 ) / 304420

= 491 / 620

= 491

Step2:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 491, 620, 764, 785 is 1
