Given numbers are 745, 840, 251, 392

The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 251 are 251

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 745, 840, 251, 392

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

Apply this formula for all numbers.

Step1:

LCM(745, 840) = 125160

GCD(745, 840) = ( 745 x 840 ) / 125160

= 745 / 840

= 745

Step2:

LCM(5, 251) = 1255

GCD(5, 251) = ( 5 x 251 ) / 1255

= 5 / 251

= 5

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 745, 840, 251, 392 is 1
