Given numbers are 850, 420, 189, 427

The list of prime factors of all numbers are

Prime factors of 850 are 2 x 5 x 5 x 17

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

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 427 are 7 x 61

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

Given numbers are 850, 420, 189, 427

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

Apply this formula for all numbers.

Step1:

LCM(850, 420) = 35700

GCD(850, 420) = ( 850 x 420 ) / 35700

= 850 / 420

= 850

Step2:

LCM(10, 189) = 1890

GCD(10, 189) = ( 10 x 189 ) / 1890

= 10 / 189

= 10

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 850, 420, 189, 427 is 1
