Given numbers are 156, 402, 521, 421

The list of prime factors of all numbers are

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 402 are 2 x 3 x 67

Prime factors of 521 are 521

Prime factors of 421 are 421

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

Given numbers are 156, 402, 521, 421

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

Apply this formula for all numbers.

Step1:

LCM(156, 402) = 10452

GCD(156, 402) = ( 156 x 402 ) / 10452

= 156 / 402

= 156

Step2:

LCM(6, 521) = 3126

GCD(6, 521) = ( 6 x 521 ) / 3126

= 6 / 521

= 6

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 156, 402, 521, 421 is 1
