Given numbers are 117, 391, 430

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

Apply this formula for all numbers.

Step1:

LCM(117, 391) = 45747

GCD(117, 391) = ( 117 x 391 ) / 45747

= 117 / 391

= 117

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 117, 391, 430 is 1
