Given numbers are 237, 662, 690, 645

The list of prime factors of all numbers are

Prime factors of 237 are 3 x 79

Prime factors of 662 are 2 x 331

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 237, 662, 690, 645

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

Apply this formula for all numbers.

Step1:

LCM(237, 662) = 156894

GCD(237, 662) = ( 237 x 662 ) / 156894

= 237 / 662

= 237

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 237, 662, 690, 645 is 1
