Given numbers are 775, 770, 542, 130

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

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

Prime factors of 542 are 2 x 271

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 775, 770, 542, 130

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

Apply this formula for all numbers.

Step1:

LCM(775, 770) = 119350

GCD(775, 770) = ( 775 x 770 ) / 119350

= 775 / 770

= 775

Step2:

LCM(5, 542) = 2710

GCD(5, 542) = ( 5 x 542 ) / 2710

= 5 / 542

= 5

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 775, 770, 542, 130 is 1
