Given numbers are 893, 285, 208, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(893, 285) = 13395
GCD(893, 285) = ( 893 x 285 ) / 13395
= 893 / 285
= 893
Step2:
LCM(19, 208) = 3952
GCD(19, 208) = ( 19 x 208 ) / 3952
= 19 / 208
= 19
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 893, 285, 208, 840 is 1
