Given numbers are 690, 185, 671, 442

The list of prime factors of all numbers are

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

Prime factors of 185 are 5 x 37

Prime factors of 671 are 11 x 61

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 690, 185, 671, 442

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

Apply this formula for all numbers.

Step1:

LCM(690, 185) = 25530

GCD(690, 185) = ( 690 x 185 ) / 25530

= 690 / 185

= 690

Step2:

LCM(5, 671) = 3355

GCD(5, 671) = ( 5 x 671 ) / 3355

= 5 / 671

= 5

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 690, 185, 671, 442 is 1
