Given numbers are 645, 253, 106, 187

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 253 are 11 x 23

Prime factors of 106 are 2 x 53

Prime factors of 187 are 11 x 17

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

Given numbers are 645, 253, 106, 187

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

Apply this formula for all numbers.

Step1:

LCM(645, 253) = 163185

GCD(645, 253) = ( 645 x 253 ) / 163185

= 645 / 253

= 645

Step2:

LCM(1, 106) = 106

GCD(1, 106) = ( 1 x 106 ) / 106

= 1 / 106

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 645, 253, 106, 187 is 1
