Given numbers are 704, 171, 854, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(704, 171) = 120384
GCD(704, 171) = ( 704 x 171 ) / 120384
= 704 / 171
= 704
Step2:
LCM(1, 854) = 854
GCD(1, 854) = ( 1 x 854 ) / 854
= 1 / 854
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 704, 171, 854, 420 is 1
