Given numbers are 771, 686, 217

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

Apply this formula for all numbers.

Step1:

LCM(771, 686) = 528906

GCD(771, 686) = ( 771 x 686 ) / 528906

= 771 / 686

= 771

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 771, 686, 217 is 1
