Given numbers are 238, 625, 78, 407

The list of prime factors of all numbers are

Prime factors of 238 are 2 x 7 x 17

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 78 are 2 x 3 x 13

Prime factors of 407 are 11 x 37

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

Given numbers are 238, 625, 78, 407

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

Apply this formula for all numbers.

Step1:

LCM(238, 625) = 148750

GCD(238, 625) = ( 238 x 625 ) / 148750

= 238 / 625

= 238

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 238, 625, 78, 407 is 1
