Given numbers are 657, 680, 678, 145

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 678 are 2 x 3 x 113

Prime factors of 145 are 5 x 29

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

Given numbers are 657, 680, 678, 145

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

Apply this formula for all numbers.

Step1:

LCM(657, 680) = 446760

GCD(657, 680) = ( 657 x 680 ) / 446760

= 657 / 680

= 657

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 657, 680, 678, 145 is 1
