Given numbers are 897, 666, 721, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 666) = 199134
GCD(897, 666) = ( 897 x 666 ) / 199134
= 897 / 666
= 897
Step2:
LCM(3, 721) = 2163
GCD(3, 721) = ( 3 x 721 ) / 2163
= 3 / 721
= 3
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 897, 666, 721, 388 is 1
