Given numbers are 423, 738, 545, 121

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 545 are 5 x 109

Prime factors of 121 are 11 x 11

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

Given numbers are 423, 738, 545, 121

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

Apply this formula for all numbers.

Step1:

LCM(423, 738) = 34686

GCD(423, 738) = ( 423 x 738 ) / 34686

= 423 / 738

= 423

Step2:

LCM(9, 545) = 4905

GCD(9, 545) = ( 9 x 545 ) / 4905

= 9 / 545

= 9

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 423, 738, 545, 121 is 1
