Given numbers are 131, 529, 840, 945

The list of prime factors of all numbers are

Prime factors of 131 are 131

Prime factors of 529 are 23 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 131, 529, 840, 945

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

Apply this formula for all numbers.

Step1:

LCM(131, 529) = 69299

GCD(131, 529) = ( 131 x 529 ) / 69299

= 131 / 529

= 131

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 131, 529, 840, 945 is 1
