Given numbers are 742, 321, 843, 402

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 321 are 3 x 107

Prime factors of 843 are 3 x 281

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 742, 321, 843, 402

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

Apply this formula for all numbers.

Step1:

LCM(742, 321) = 238182

GCD(742, 321) = ( 742 x 321 ) / 238182

= 742 / 321

= 742

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 402) = 402

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

= 1 / 402

= 1

So, Greatest Common Divisor of 742, 321, 843, 402 is 1
