Given numbers are 285, 705, 912, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 705) = 13395
GCD(285, 705) = ( 285 x 705 ) / 13395
= 285 / 705
= 285
Step2:
LCM(15, 912) = 4560
GCD(15, 912) = ( 15 x 912 ) / 4560
= 15 / 912
= 15
Step3:
LCM(3, 671) = 2013
GCD(3, 671) = ( 3 x 671 ) / 2013
= 3 / 671
= 3
So, Greatest Common Divisor of 285, 705, 912, 671 is 1
