Given numbers are 546, 639, 440, 520

The list of prime factors of all numbers are

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 639 are 3 x 3 x 71

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 546, 639, 440, 520

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

Apply this formula for all numbers.

Step1:

LCM(546, 639) = 116298

GCD(546, 639) = ( 546 x 639 ) / 116298

= 546 / 639

= 546

Step2:

LCM(3, 440) = 1320

GCD(3, 440) = ( 3 x 440 ) / 1320

= 3 / 440

= 3

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 546, 639, 440, 520 is 1
