Given numbers are 894, 129, 286, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(894, 129) = 38442
GCD(894, 129) = ( 894 x 129 ) / 38442
= 894 / 129
= 894
Step2:
LCM(3, 286) = 858
GCD(3, 286) = ( 3 x 286 ) / 858
= 3 / 286
= 3
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 894, 129, 286, 840 is 1
