Given numbers are 210, 209, 715, 999

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

Apply this formula for all numbers.

Step1:

LCM(210, 209) = 43890

GCD(210, 209) = ( 210 x 209 ) / 43890

= 210 / 209

= 210

Step2:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

Step3:

LCM(1, 999) = 999

GCD(1, 999) = ( 1 x 999 ) / 999

= 1 / 999

= 1

So, Greatest Common Divisor of 210, 209, 715, 999 is 1
