Given numbers are 455, 377, 577, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 377) = 13195
GCD(455, 377) = ( 455 x 377 ) / 13195
= 455 / 377
= 455
Step2:
LCM(13, 577) = 7501
GCD(13, 577) = ( 13 x 577 ) / 7501
= 13 / 577
= 13
Step3:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
So, Greatest Common Divisor of 455, 377, 577, 985 is 1
