Given numbers are 770, 905, 762, 430

The list of prime factors of all numbers are

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

Prime factors of 905 are 5 x 181

Prime factors of 762 are 2 x 3 x 127

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 770, 905, 762, 430

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

Apply this formula for all numbers.

Step1:

LCM(770, 905) = 139370

GCD(770, 905) = ( 770 x 905 ) / 139370

= 770 / 905

= 770

Step2:

LCM(5, 762) = 3810

GCD(5, 762) = ( 5 x 762 ) / 3810

= 5 / 762

= 5

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 770, 905, 762, 430 is 1
