Given numbers are 686, 838, 915, 854
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 838) = 287434
GCD(686, 838) = ( 686 x 838 ) / 287434
= 686 / 838
= 686
Step2:
LCM(2, 915) = 1830
GCD(2, 915) = ( 2 x 915 ) / 1830
= 2 / 915
= 2
Step3:
LCM(1, 854) = 854
GCD(1, 854) = ( 1 x 854 ) / 854
= 1 / 854
= 1
So, Greatest Common Divisor of 686, 838, 915, 854 is 1
