Given numbers are 663, 448, 761, 434

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 761 are 761

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 663, 448, 761, 434

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

Apply this formula for all numbers.

Step1:

LCM(663, 448) = 297024

GCD(663, 448) = ( 663 x 448 ) / 297024

= 663 / 448

= 663

Step2:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 663, 448, 761, 434 is 1
