Given numbers are 170, 920, 397, 919

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

Apply this formula for all numbers.

Step1:

LCM(170, 920) = 15640

GCD(170, 920) = ( 170 x 920 ) / 15640

= 170 / 920

= 170

Step2:

LCM(10, 397) = 3970

GCD(10, 397) = ( 10 x 397 ) / 3970

= 10 / 397

= 10

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 170, 920, 397, 919 is 1
