Given numbers are 430, 635, 985, 209

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

Apply this formula for all numbers.

Step1:

LCM(430, 635) = 54610

GCD(430, 635) = ( 430 x 635 ) / 54610

= 430 / 635

= 430

Step2:

LCM(5, 985) = 985

GCD(5, 985) = ( 5 x 985 ) / 985

= 5 / 985

= 5

Step3:

LCM(5, 209) = 1045

GCD(5, 209) = ( 5 x 209 ) / 1045

= 5 / 209

= 5

So, Greatest Common Divisor of 430, 635, 985, 209 is 1
