Given numbers are 638, 186, 662, 145

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 186 are 2 x 3 x 31

Prime factors of 662 are 2 x 331

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 638, 186, 662, 145

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

Apply this formula for all numbers.

Step1:

LCM(638, 186) = 59334

GCD(638, 186) = ( 638 x 186 ) / 59334

= 638 / 186

= 638

Step2:

LCM(2, 662) = 662

GCD(2, 662) = ( 2 x 662 ) / 662

= 2 / 662

= 2

Step3:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

So, Greatest Common Divisor of 638, 186, 662, 145 is 1
