Given numbers are 707, 425, 786, 420

The list of prime factors of all numbers are

Prime factors of 707 are 7 x 101

Prime factors of 425 are 5 x 5 x 17

Prime factors of 786 are 2 x 3 x 131

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 707, 425, 786, 420

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

Apply this formula for all numbers.

Step1:

LCM(707, 425) = 300475

GCD(707, 425) = ( 707 x 425 ) / 300475

= 707 / 425

= 707

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 707, 425, 786, 420 is 1
