Given numbers are 684, 399, 386, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 399) = 4788
GCD(684, 399) = ( 684 x 399 ) / 4788
= 684 / 399
= 684
Step2:
LCM(57, 386) = 22002
GCD(57, 386) = ( 57 x 386 ) / 22002
= 57 / 386
= 57
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 684, 399, 386, 215 is 1
