Given numbers are 398, 574, 905, 854
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 574) = 114226
GCD(398, 574) = ( 398 x 574 ) / 114226
= 398 / 574
= 398
Step2:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
Step3:
LCM(1, 854) = 854
GCD(1, 854) = ( 1 x 854 ) / 854
= 1 / 854
= 1
So, Greatest Common Divisor of 398, 574, 905, 854 is 1
