Given numbers are 770, 438, 102, 235

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 438 are 2 x 3 x 73

Prime factors of 102 are 2 x 3 x 17

Prime factors of 235 are 5 x 47

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

Given numbers are 770, 438, 102, 235

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

Apply this formula for all numbers.

Step1:

LCM(770, 438) = 168630

GCD(770, 438) = ( 770 x 438 ) / 168630

= 770 / 438

= 770

Step2:

LCM(2, 102) = 102

GCD(2, 102) = ( 2 x 102 ) / 102

= 2 / 102

= 2

Step3:

LCM(2, 235) = 470

GCD(2, 235) = ( 2 x 235 ) / 470

= 2 / 235

= 2

So, Greatest Common Divisor of 770, 438, 102, 235 is 1
