Given numbers are 981, 236, 839, 720

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 236 are 2 x 2 x 59

Prime factors of 839 are 839

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 981, 236, 839, 720

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

Apply this formula for all numbers.

Step1:

LCM(981, 236) = 231516

GCD(981, 236) = ( 981 x 236 ) / 231516

= 981 / 236

= 981

Step2:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 981, 236, 839, 720 is 1
