Given numbers are 436, 420, 773, 558

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

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

Prime factors of 773 are 773

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 436, 420, 773, 558

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

Apply this formula for all numbers.

Step1:

LCM(436, 420) = 45780

GCD(436, 420) = ( 436 x 420 ) / 45780

= 436 / 420

= 436

Step2:

LCM(4, 773) = 3092

GCD(4, 773) = ( 4 x 773 ) / 3092

= 4 / 773

= 4

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 436, 420, 773, 558 is 1
