Given numbers are 420, 103, 827, 866

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 103 are 103

Prime factors of 827 are 827

Prime factors of 866 are 2 x 433

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

Given numbers are 420, 103, 827, 866

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

Apply this formula for all numbers.

Step1:

LCM(420, 103) = 43260

GCD(420, 103) = ( 420 x 103 ) / 43260

= 420 / 103

= 420

Step2:

LCM(1, 827) = 827

GCD(1, 827) = ( 1 x 827 ) / 827

= 1 / 827

= 1

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 420, 103, 827, 866 is 1
