Given numbers are 457, 443, 385, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 443) = 202451
GCD(457, 443) = ( 457 x 443 ) / 202451
= 457 / 443
= 457
Step2:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 457, 443, 385, 456 is 1
