Given numbers are 194, 690, 639, 450

The list of prime factors of all numbers are

Prime factors of 194 are 2 x 97

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 194, 690, 639, 450

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

Apply this formula for all numbers.

Step1:

LCM(194, 690) = 66930

GCD(194, 690) = ( 194 x 690 ) / 66930

= 194 / 690

= 194

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 194, 690, 639, 450 is 1
