Given numbers are 238, 981, 77, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 981) = 233478
GCD(238, 981) = ( 238 x 981 ) / 233478
= 238 / 981
= 238
Step2:
LCM(1, 77) = 77
GCD(1, 77) = ( 1 x 77 ) / 77
= 1 / 77
= 1
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 238, 981, 77, 393 is 1
