Given numbers are 455, 305, 387, 894
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 305) = 27755
GCD(455, 305) = ( 455 x 305 ) / 27755
= 455 / 305
= 455
Step2:
LCM(5, 387) = 1935
GCD(5, 387) = ( 5 x 387 ) / 1935
= 5 / 387
= 5
Step3:
LCM(1, 894) = 894
GCD(1, 894) = ( 1 x 894 ) / 894
= 1 / 894
= 1
So, Greatest Common Divisor of 455, 305, 387, 894 is 1
