Given numbers are 666, 437, 391, 199
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 437) = 291042
GCD(666, 437) = ( 666 x 437 ) / 291042
= 666 / 437
= 666
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 199) = 199
GCD(1, 199) = ( 1 x 199 ) / 199
= 1 / 199
= 1
So, Greatest Common Divisor of 666, 437, 391, 199 is 1
