Given numbers are 980, 565, 780, 247

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 565 are 5 x 113

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

Prime factors of 247 are 13 x 19

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

Given numbers are 980, 565, 780, 247

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

Apply this formula for all numbers.

Step1:

LCM(980, 565) = 110740

GCD(980, 565) = ( 980 x 565 ) / 110740

= 980 / 565

= 980

Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

Step3:

LCM(5, 247) = 1235

GCD(5, 247) = ( 5 x 247 ) / 1235

= 5 / 247

= 5

So, Greatest Common Divisor of 980, 565, 780, 247 is 1
