Given numbers are 218, 388, 11, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 388) = 42292
GCD(218, 388) = ( 218 x 388 ) / 42292
= 218 / 388
= 218
Step2:
LCM(2, 11) = 22
GCD(2, 11) = ( 2 x 11 ) / 22
= 2 / 11
= 2
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 218, 388, 11, 990 is 1
