GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 681) = 271038
GCD(398, 681) = ( 398 x 681 ) / 271038
= 398 / 681
= 398
Step2:
LCM(1, 359) = 359
GCD(1, 359) = ( 1 x 359 ) / 359
= 1 / 359
= 1
Step3:
LCM(1, 312) = 312
GCD(1, 312) = ( 1 x 312 ) / 312
= 1 / 312
= 1
So, Greatest Common Divisor of 398, 681, 359, 312 is 1
