Given numbers are 157, 455, 336, 689

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 455 are 5 x 7 x 13

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 689 are 13 x 53

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

Given numbers are 157, 455, 336, 689

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

Apply this formula for all numbers.

Step1:

LCM(157, 455) = 71435

GCD(157, 455) = ( 157 x 455 ) / 71435

= 157 / 455

= 157

Step2:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 157, 455, 336, 689 is 1
