Given numbers are 690, 835, 538, 945

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 835 are 5 x 167

Prime factors of 538 are 2 x 269

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 690, 835, 538, 945

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

Apply this formula for all numbers.

Step1:

LCM(690, 835) = 115230

GCD(690, 835) = ( 690 x 835 ) / 115230

= 690 / 835

= 690

Step2:

LCM(5, 538) = 2690

GCD(5, 538) = ( 5 x 538 ) / 2690

= 5 / 538

= 5

Step3:

LCM(1, 945) = 945

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

= 1 / 945

= 1

So, Greatest Common Divisor of 690, 835, 538, 945 is 1
