Given numbers are 775, 780, 635, 154

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 635 are 5 x 127

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 775, 780, 635, 154

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

Apply this formula for all numbers.

Step1:

LCM(775, 780) = 120900

GCD(775, 780) = ( 775 x 780 ) / 120900

= 775 / 780

= 775

Step2:

LCM(5, 635) = 635

GCD(5, 635) = ( 5 x 635 ) / 635

= 5 / 635

= 5

Step3:

LCM(5, 154) = 770

GCD(5, 154) = ( 5 x 154 ) / 770

= 5 / 154

= 5

So, Greatest Common Divisor of 775, 780, 635, 154 is 1
