Given numbers are 690, 416, 197, 242

The list of prime factors of all numbers are

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

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 197 are 197

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 690, 416, 197, 242

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

Apply this formula for all numbers.

Step1:

LCM(690, 416) = 143520

GCD(690, 416) = ( 690 x 416 ) / 143520

= 690 / 416

= 690

Step2:

LCM(2, 197) = 394

GCD(2, 197) = ( 2 x 197 ) / 394

= 2 / 197

= 2

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 690, 416, 197, 242 is 1
