The list of prime factors of all numbers are

Prime factors of 692 are 2 x 2 x 173

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 649 are 11 x 59

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

Given numbers are 692, 620, 780, 649

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

Apply this formula for all numbers.

Step1:

LCM(692, 620) = 107260

GCD(692, 620) = ( 692 x 620 ) / 107260

= 692 / 620

= 692

Step2:

LCM(4, 780) = 780

GCD(4, 780) = ( 4 x 780 ) / 780

= 4 / 780

= 4

Step3:

LCM(4, 649) = 2596

GCD(4, 649) = ( 4 x 649 ) / 2596

= 4 / 649

= 4

So, Greatest Common Divisor of 692, 620, 780, 649 is 1
