Given numbers are 546, 621, 513, 661

The list of prime factors of all numbers are

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

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 661 are 661

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

Given numbers are 546, 621, 513, 661

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

Apply this formula for all numbers.

Step1:

LCM(546, 621) = 113022

GCD(546, 621) = ( 546 x 621 ) / 113022

= 546 / 621

= 546

Step2:

LCM(3, 513) = 513

GCD(3, 513) = ( 3 x 513 ) / 513

= 3 / 513

= 3

Step3:

LCM(3, 661) = 1983

GCD(3, 661) = ( 3 x 661 ) / 1983

= 3 / 661

= 3

So, Greatest Common Divisor of 546, 621, 513, 661 is 1
