Given numbers are 217, 986, 797, 248
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 986) = 213962
GCD(217, 986) = ( 217 x 986 ) / 213962
= 217 / 986
= 217
Step2:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
Step3:
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
= 1 / 248
= 1
So, Greatest Common Divisor of 217, 986, 797, 248 is 1
