GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 997) = 675966
GCD(678, 997) = ( 678 x 997 ) / 675966
= 678 / 997
= 678
Step2:
LCM(1, 539) = 539
GCD(1, 539) = ( 1 x 539 ) / 539
= 1 / 539
= 1
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 678, 997, 539, 787 is 1
