Given numbers are 342, 665, 980, 854
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(342, 665) = 11970
GCD(342, 665) = ( 342 x 665 ) / 11970
= 342 / 665
= 342
Step2:
LCM(19, 980) = 18620
GCD(19, 980) = ( 19 x 980 ) / 18620
= 19 / 980
= 19
Step3:
LCM(1, 854) = 854
GCD(1, 854) = ( 1 x 854 ) / 854
= 1 / 854
= 1
So, Greatest Common Divisor of 342, 665, 980, 854 is 1
