Given numbers are 455, 628, 214, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 628) = 285740
GCD(455, 628) = ( 455 x 628 ) / 285740
= 455 / 628
= 455
Step2:
LCM(1, 214) = 214
GCD(1, 214) = ( 1 x 214 ) / 214
= 1 / 214
= 1
Step3:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
So, Greatest Common Divisor of 455, 628, 214, 863 is 1
