Given numbers are 430, 548, 402, 253

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 548 are 2 x 2 x 137

Prime factors of 402 are 2 x 3 x 67

Prime factors of 253 are 11 x 23

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

Given numbers are 430, 548, 402, 253

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

Apply this formula for all numbers.

Step1:

LCM(430, 548) = 117820

GCD(430, 548) = ( 430 x 548 ) / 117820

= 430 / 548

= 430

Step2:

LCM(2, 402) = 402

GCD(2, 402) = ( 2 x 402 ) / 402

= 2 / 402

= 2

Step3:

LCM(2, 253) = 506

GCD(2, 253) = ( 2 x 253 ) / 506

= 2 / 253

= 2

So, Greatest Common Divisor of 430, 548, 402, 253 is 1
