Given numbers are 980, 142, 692, 805

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 142 are 2 x 71

Prime factors of 692 are 2 x 2 x 173

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 980, 142, 692, 805

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

Apply this formula for all numbers.

Step1:

LCM(980, 142) = 69580

GCD(980, 142) = ( 980 x 142 ) / 69580

= 980 / 142

= 980

Step2:

LCM(2, 692) = 692

GCD(2, 692) = ( 2 x 692 ) / 692

= 2 / 692

= 2

Step3:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

So, Greatest Common Divisor of 980, 142, 692, 805 is 1
