Given numbers are 398, 294, 463, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 294) = 58506
GCD(398, 294) = ( 398 x 294 ) / 58506
= 398 / 294
= 398
Step2:
LCM(2, 463) = 926
GCD(2, 463) = ( 2 x 463 ) / 926
= 2 / 463
= 2
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 398, 294, 463, 245 is 1
