So, the GCD (644, 550, 85, 836) = 1.

Given numbers are 644, 550, 85, 836

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

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

Prime factors of 85 are 5 x 17

Prime factors of 836 are 2 x 2 x 11 x 19

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

Given numbers are 644, 550, 85, 836

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

Apply this formula for all numbers.

Step1:

LCM(644, 550) = 177100

GCD(644, 550) = ( 644 x 550 ) / 177100

= 644 / 550

= 644

Step2:

LCM(2, 85) = 170

GCD(2, 85) = ( 2 x 85 ) / 170

= 2 / 85

= 2

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 644, 550, 85, 836 is 1
