Given numbers are 399, 787, 245, 318
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 787) = 314013
GCD(399, 787) = ( 399 x 787 ) / 314013
= 399 / 787
= 399
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
= 1 / 318
= 1
So, Greatest Common Divisor of 399, 787, 245, 318 is 1
