Given numbers are 217, 991, 237, 749
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 991) = 215047
GCD(217, 991) = ( 217 x 991 ) / 215047
= 217 / 991
= 217
Step2:
LCM(1, 237) = 237
GCD(1, 237) = ( 1 x 237 ) / 237
= 1 / 237
= 1
Step3:
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
= 1 / 749
= 1
So, Greatest Common Divisor of 217, 991, 237, 749 is 1
