Given numbers are 818, 655, 696, 620

The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 655 are 5 x 131

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 620 are 2 x 2 x 5 x 31

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 818, 655, 696, 620

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

Apply this formula for all numbers.

Step1:

LCM(818, 655) = 535790

GCD(818, 655) = ( 818 x 655 ) / 535790

= 818 / 655

= 818

Step2:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 818, 655, 696, 620 is 1
