Given numbers are 209, 778, 140

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

Apply this formula for all numbers.

Step1:

LCM(209, 778) = 162602

GCD(209, 778) = ( 209 x 778 ) / 162602

= 209 / 778

= 209

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 209, 778, 140 is 1
