Given numbers are 774, 782, 178, 217

The list of prime factors of all numbers are

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 782 are 2 x 17 x 23

Prime factors of 178 are 2 x 89

Prime factors of 217 are 7 x 31

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

Given numbers are 774, 782, 178, 217

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

Apply this formula for all numbers.

Step1:

LCM(774, 782) = 302634

GCD(774, 782) = ( 774 x 782 ) / 302634

= 774 / 782

= 774

Step2:

LCM(2, 178) = 178

GCD(2, 178) = ( 2 x 178 ) / 178

= 2 / 178

= 2

Step3:

LCM(2, 217) = 434

GCD(2, 217) = ( 2 x 217 ) / 434

= 2 / 217

= 2

So, Greatest Common Divisor of 774, 782, 178, 217 is 1
