Given numbers are 981, 393, 437, 308
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 393) = 128511
GCD(981, 393) = ( 981 x 393 ) / 128511
= 981 / 393
= 981
Step2:
LCM(3, 437) = 1311
GCD(3, 437) = ( 3 x 437 ) / 1311
= 3 / 437
= 3
Step3:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
So, Greatest Common Divisor of 981, 393, 437, 308 is 1
