Given numbers are 556, 390, 191, 214
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 390) = 108420
GCD(556, 390) = ( 556 x 390 ) / 108420
= 556 / 390
= 556
Step2:
LCM(2, 191) = 382
GCD(2, 191) = ( 2 x 191 ) / 382
= 2 / 191
= 2
Step3:
LCM(1, 214) = 214
GCD(1, 214) = ( 1 x 214 ) / 214
= 1 / 214
= 1
So, Greatest Common Divisor of 556, 390, 191, 214 is 1
