Given numbers are 281, 658, 961, 780

The list of prime factors of all numbers are

Prime factors of 281 are 281

Prime factors of 658 are 2 x 7 x 47

Prime factors of 961 are 31 x 31

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 281, 658, 961, 780

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

Apply this formula for all numbers.

Step1:

LCM(281, 658) = 184898

GCD(281, 658) = ( 281 x 658 ) / 184898

= 281 / 658

= 281

Step2:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 281, 658, 961, 780 is 1
