Given numbers are 689, 388, 890, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 388) = 267332
GCD(689, 388) = ( 689 x 388 ) / 267332
= 689 / 388
= 689
Step2:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 689, 388, 890, 223 is 1
