Given numbers are 285, 183, 680, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 183) = 17385
GCD(285, 183) = ( 285 x 183 ) / 17385
= 285 / 183
= 285
Step2:
LCM(3, 680) = 2040
GCD(3, 680) = ( 3 x 680 ) / 2040
= 3 / 680
= 3
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 285, 183, 680, 705 is 1
