Given numbers are 236, 338, 407, 420

The list of prime factors of all numbers are

Prime factors of 236 are 2 x 2 x 59

Prime factors of 338 are 2 x 13 x 13

Prime factors of 407 are 11 x 37

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 236, 338, 407, 420

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

Apply this formula for all numbers.

Step1:

LCM(236, 338) = 39884

GCD(236, 338) = ( 236 x 338 ) / 39884

= 236 / 338

= 236

Step2:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 236, 338, 407, 420 is 1
