Given numbers are 504, 393, 687, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(504, 393) = 66024
GCD(504, 393) = ( 504 x 393 ) / 66024
= 504 / 393
= 504
Step2:
LCM(3, 687) = 687
GCD(3, 687) = ( 3 x 687 ) / 687
= 3 / 687
= 3
Step3:
LCM(3, 397) = 1191
GCD(3, 397) = ( 3 x 397 ) / 1191
= 3 / 397
= 3
So, Greatest Common Divisor of 504, 393, 687, 397 is 1
