The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

Prime factors of 981 are 3 x 3 x 109

Prime factors of 824 are 2 x 2 x 2 x 103

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

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

Given numbers are 411, 981, 824, 780

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

Apply this formula for all numbers.

Step1:

LCM(411, 981) = 134397

GCD(411, 981) = ( 411 x 981 ) / 134397

= 411 / 981

= 411

Step2:

LCM(3, 824) = 2472

GCD(3, 824) = ( 3 x 824 ) / 2472

= 3 / 824

= 3

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 411, 981, 824, 780 is 1
