Given numbers are 420, 753, 206, 428

The list of prime factors of all numbers are

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

Prime factors of 753 are 3 x 251

Prime factors of 206 are 2 x 103

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 420, 753, 206, 428

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

Apply this formula for all numbers.

Step1:

LCM(420, 753) = 105420

GCD(420, 753) = ( 420 x 753 ) / 105420

= 420 / 753

= 420

Step2:

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

= 3 / 206

= 3

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 420, 753, 206, 428 is 1
