Given numbers are 890, 152, 644, 257

The list of prime factors of all numbers are

Prime factors of 890 are 2 x 5 x 89

Prime factors of 152 are 2 x 2 x 2 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 257 are 257

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

Given numbers are 890, 152, 644, 257

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

Apply this formula for all numbers.

Step1:

LCM(890, 152) = 67640

GCD(890, 152) = ( 890 x 152 ) / 67640

= 890 / 152

= 890

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 890, 152, 644, 257 is 1
