Given numbers are 238, 660, 155, 662

The list of prime factors of all numbers are

Prime factors of 238 are 2 x 7 x 17

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 155 are 5 x 31

Prime factors of 662 are 2 x 331

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

Given numbers are 238, 660, 155, 662

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

Apply this formula for all numbers.

Step1:

LCM(238, 660) = 78540

GCD(238, 660) = ( 238 x 660 ) / 78540

= 238 / 660

= 238

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 238, 660, 155, 662 is 1
