Given numbers are 866, 761, 125, 420

The list of prime factors of all numbers are

Prime factors of 866 are 2 x 433

Prime factors of 761 are 761

Prime factors of 125 are 5 x 5 x 5

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 866, 761, 125, 420

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

Apply this formula for all numbers.

Step1:

LCM(866, 761) = 659026

GCD(866, 761) = ( 866 x 761 ) / 659026

= 866 / 761

= 866

Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 866, 761, 125, 420 is 1
