Given numbers are 251, 445, 605, 665

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

Apply this formula for all numbers.

Step1:

LCM(251, 445) = 111695

GCD(251, 445) = ( 251 x 445 ) / 111695

= 251 / 445

= 251

Step2:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 251, 445, 605, 665 is 1
