Given numbers are 981, 910, 257, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 910) = 892710
GCD(981, 910) = ( 981 x 910 ) / 892710
= 981 / 910
= 981
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 981, 910, 257, 223 is 1
