Given numbers are 217, 418, 78, 922

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

Apply this formula for all numbers.

Step1:

LCM(217, 418) = 90706

GCD(217, 418) = ( 217 x 418 ) / 90706

= 217 / 418

= 217

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

= 1 / 922

= 1

So, Greatest Common Divisor of 217, 418, 78, 922 is 1
