Given numbers are 981, 495, 728, 698

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 698 are 2 x 349

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

Given numbers are 981, 495, 728, 698

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

Apply this formula for all numbers.

Step1:

LCM(981, 495) = 53955

GCD(981, 495) = ( 981 x 495 ) / 53955

= 981 / 495

= 981

Step2:

LCM(9, 728) = 6552

GCD(9, 728) = ( 9 x 728 ) / 6552

= 9 / 728

= 9

Step3:

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

= 1 / 698

= 1

So, Greatest Common Divisor of 981, 495, 728, 698 is 1
