Given numbers are 406, 665, 77, 897
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 665) = 38570
GCD(406, 665) = ( 406 x 665 ) / 38570
= 406 / 665
= 406
Step2:
LCM(7, 77) = 77
GCD(7, 77) = ( 7 x 77 ) / 77
= 7 / 77
= 7
Step3:
LCM(7, 897) = 6279
GCD(7, 897) = ( 7 x 897 ) / 6279
= 7 / 897
= 7
So, Greatest Common Divisor of 406, 665, 77, 897 is 1
