Given numbers are 655, 408, 890, 938

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 890 are 2 x 5 x 89

Prime factors of 938 are 2 x 7 x 67

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

Given numbers are 655, 408, 890, 938

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

Apply this formula for all numbers.

Step1:

LCM(655, 408) = 267240

GCD(655, 408) = ( 655 x 408 ) / 267240

= 655 / 408

= 655

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 938) = 938

GCD(1, 938) = ( 1 x 938 ) / 938

= 1 / 938

= 1

So, Greatest Common Divisor of 655, 408, 890, 938 is 1
