Given numbers are 345, 147, 209, 170

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

Apply this formula for all numbers.

Step1:

LCM(345, 147) = 16905

GCD(345, 147) = ( 345 x 147 ) / 16905

= 345 / 147

= 345

Step2:

LCM(3, 209) = 627

GCD(3, 209) = ( 3 x 209 ) / 627

= 3 / 209

= 3

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 345, 147, 209, 170 is 1
