Given numbers are 982, 278, 780, 575

The list of prime factors of all numbers are

Prime factors of 982 are 2 x 491

Prime factors of 278 are 2 x 139

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

Prime factors of 575 are 5 x 5 x 23

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

Given numbers are 982, 278, 780, 575

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

Apply this formula for all numbers.

Step1:

LCM(982, 278) = 136498

GCD(982, 278) = ( 982 x 278 ) / 136498

= 982 / 278

= 982

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 575) = 1150

GCD(2, 575) = ( 2 x 575 ) / 1150

= 2 / 575

= 2

So, Greatest Common Divisor of 982, 278, 780, 575 is 1
