Given numbers are 217, 771, 929, 406

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

Apply this formula for all numbers.

Step1:

LCM(217, 771) = 167307

GCD(217, 771) = ( 217 x 771 ) / 167307

= 217 / 771

= 217

Step2:

LCM(1, 929) = 929

GCD(1, 929) = ( 1 x 929 ) / 929

= 1 / 929

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 217, 771, 929, 406 is 1
