Given numbers are 761, 198, 614, 420

The list of prime factors of all numbers are

Prime factors of 761 are 761

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 614 are 2 x 307

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 761, 198, 614, 420

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

Apply this formula for all numbers.

Step1:

LCM(761, 198) = 150678

GCD(761, 198) = ( 761 x 198 ) / 150678

= 761 / 198

= 761

Step2:

LCM(1, 614) = 614

GCD(1, 614) = ( 1 x 614 ) / 614

= 1 / 614

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 761, 198, 614, 420 is 1
