Given numbers are 665, 984, 820, 550

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

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

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 665, 984, 820, 550

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

Apply this formula for all numbers.

Step1:

LCM(665, 984) = 654360

GCD(665, 984) = ( 665 x 984 ) / 654360

= 665 / 984

= 665

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 665, 984, 820, 550 is 1
