Given numbers are 645, 654, 412, 526

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 654 are 2 x 3 x 109

Prime factors of 412 are 2 x 2 x 103

Prime factors of 526 are 2 x 263

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

Given numbers are 645, 654, 412, 526

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

Apply this formula for all numbers.

Step1:

LCM(645, 654) = 140610

GCD(645, 654) = ( 645 x 654 ) / 140610

= 645 / 654

= 645

Step2:

LCM(3, 412) = 1236

GCD(3, 412) = ( 3 x 412 ) / 1236

= 3 / 412

= 3

Step3:

LCM(1, 526) = 526

GCD(1, 526) = ( 1 x 526 ) / 526

= 1 / 526

= 1

So, Greatest Common Divisor of 645, 654, 412, 526 is 1
