Given numbers are 612, 398, 698, 545

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 398 are 2 x 199

Prime factors of 698 are 2 x 349

Prime factors of 545 are 5 x 109

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

Given numbers are 612, 398, 698, 545

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

Apply this formula for all numbers.

Step1:

LCM(612, 398) = 121788

GCD(612, 398) = ( 612 x 398 ) / 121788

= 612 / 398

= 612

Step2:

LCM(2, 698) = 698

GCD(2, 698) = ( 2 x 698 ) / 698

= 2 / 698

= 2

Step3:

LCM(2, 545) = 1090

GCD(2, 545) = ( 2 x 545 ) / 1090

= 2 / 545

= 2

So, Greatest Common Divisor of 612, 398, 698, 545 is 1
