Given numbers are 186, 148, 645, 643

The list of prime factors of all numbers are

Prime factors of 186 are 2 x 3 x 31

Prime factors of 148 are 2 x 2 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 643 are 643

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

Given numbers are 186, 148, 645, 643

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

Apply this formula for all numbers.

Step1:

LCM(186, 148) = 13764

GCD(186, 148) = ( 186 x 148 ) / 13764

= 186 / 148

= 186

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 186, 148, 645, 643 is 1
