Given numbers are 821, 712, 402, 604

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 402 are 2 x 3 x 67

Prime factors of 604 are 2 x 2 x 151

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

Given numbers are 821, 712, 402, 604

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

Apply this formula for all numbers.

Step1:

LCM(821, 712) = 584552

GCD(821, 712) = ( 821 x 712 ) / 584552

= 821 / 712

= 821

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

= 1 / 604

= 1

So, Greatest Common Divisor of 821, 712, 402, 604 is 1
