GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 991) = 482617
GCD(487, 991) = ( 487 x 991 ) / 482617
= 487 / 991
= 487
Step2:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
Step3:
LCM(1, 383) = 383
GCD(1, 383) = ( 1 x 383 ) / 383
= 1 / 383
= 1
So, Greatest Common Divisor of 487, 991, 406, 383 is 1
