Given numbers are 782, 597, 67, 420

The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 597 are 3 x 199

Prime factors of 67 are 67

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 782, 597, 67, 420

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

Apply this formula for all numbers.

Step1:

LCM(782, 597) = 466854

GCD(782, 597) = ( 782 x 597 ) / 466854

= 782 / 597

= 782

Step2:

LCM(1, 67) = 67

GCD(1, 67) = ( 1 x 67 ) / 67

= 1 / 67

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 782, 597, 67, 420 is 1
