Given numbers are 55, 97, 94, 21

The list of prime factors of all numbers are

Prime factors of 55 are 5 x 11

Prime factors of 97 are 97

Prime factors of 94 are 2 x 47

Prime factors of 21 are 3 x 7

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

Given numbers are 55, 97, 94, 21

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

Apply this formula for all numbers.

Step1:

LCM(55, 97) = 5335

GCD(55, 97) = ( 55 x 97 ) / 5335

= 55 / 97

= 55

Step2:

LCM(1, 94) = 94

GCD(1, 94) = ( 1 x 94 ) / 94

= 1 / 94

= 1

Step3:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

So, Greatest Common Divisor of 55, 97, 94, 21 is 1
