Given numbers are 258, 120, 997, 617

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

Apply this formula for all numbers.

Step1:

LCM(258, 120) = 5160

GCD(258, 120) = ( 258 x 120 ) / 5160

= 258 / 120

= 258

Step2:

LCM(6, 997) = 5982

GCD(6, 997) = ( 6 x 997 ) / 5982

= 6 / 997

= 6

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 258, 120, 997, 617 is 1
