Given numbers are 390, 189, 131, 132

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 131 are 131

Prime factors of 132 are 2 x 2 x 3 x 11

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

Given numbers are 390, 189, 131, 132

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

Apply this formula for all numbers.

Step1:

LCM(390, 189) = 24570

GCD(390, 189) = ( 390 x 189 ) / 24570

= 390 / 189

= 390

Step2:

LCM(3, 131) = 393

GCD(3, 131) = ( 3 x 131 ) / 393

= 3 / 131

= 3

Step3:

LCM(1, 132) = 132

GCD(1, 132) = ( 1 x 132 ) / 132

= 1 / 132

= 1

So, Greatest Common Divisor of 390, 189, 131, 132 is 1
