Given numbers are 658, 308, 285, 111
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 308) = 14476
GCD(658, 308) = ( 658 x 308 ) / 14476
= 658 / 308
= 658
Step2:
LCM(14, 285) = 3990
GCD(14, 285) = ( 14 x 285 ) / 3990
= 14 / 285
= 14
Step3:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
So, Greatest Common Divisor of 658, 308, 285, 111 is 1
