Given numbers are 891, 720, 761, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 720) = 71280
GCD(891, 720) = ( 891 x 720 ) / 71280
= 891 / 720
= 891
Step2:
LCM(9, 761) = 6849
GCD(9, 761) = ( 9 x 761 ) / 6849
= 9 / 761
= 9
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 891, 720, 761, 223 is 1
