Given numbers are 645, 645, 976, 786

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 645 are 3 x 5 x 43

Prime factors of 976 are 2 x 2 x 2 x 2 x 61

Prime factors of 786 are 2 x 3 x 131

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

Given numbers are 645, 645, 976, 786

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

Apply this formula for all numbers.

Step1:

LCM(645, 645) = 645

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

= 645 / 645

= 645

Step2:

LCM(645, 976) = 629520

GCD(645, 976) = ( 645 x 976 ) / 629520

= 645 / 976

= 645

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 645, 645, 976, 786 is 1
