Given numbers are 378, 791, 503, 620

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 791 are 7 x 113

Prime factors of 503 are 503

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 378, 791, 503, 620

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

Apply this formula for all numbers.

Step1:

LCM(378, 791) = 42714

GCD(378, 791) = ( 378 x 791 ) / 42714

= 378 / 791

= 378

Step2:

LCM(7, 503) = 3521

GCD(7, 503) = ( 7 x 503 ) / 3521

= 7 / 503

= 7

Step3:

LCM(1, 620) = 620

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

= 1 / 620

= 1

So, Greatest Common Divisor of 378, 791, 503, 620 is 1
