Given numbers are 109, 661, 381, 173

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

Apply this formula for all numbers.

Step1:

LCM(109, 661) = 72049

GCD(109, 661) = ( 109 x 661 ) / 72049

= 109 / 661

= 109

Step2:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 109, 661, 381, 173 is 1
