Given numbers are 820, 194, 820, 649

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 194 are 2 x 97

Prime factors of 820 are 2 x 2 x 5 x 41

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 820, 194, 820, 649

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

Apply this formula for all numbers.

Step1:

LCM(820, 194) = 79540

GCD(820, 194) = ( 820 x 194 ) / 79540

= 820 / 194

= 820

Step2:

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

= 2 / 820

= 2

Step3:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

So, Greatest Common Divisor of 820, 194, 820, 649 is 1
