Given numbers are 456, 280, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(456, 280) = 15960
GCD(456, 280) = ( 456 x 280 ) / 15960
= 456 / 280
= 456
Step2:
LCM(8, 285) = 2280
GCD(8, 285) = ( 8 x 285 ) / 2280
= 8 / 285
= 8
So, Greatest Common Divisor of 456, 280, 285 is 1
