GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 395) = 387495
GCD(981, 395) = ( 981 x 395 ) / 387495
= 981 / 395
= 981
Step2:
LCM(1, 792) = 792
GCD(1, 792) = ( 1 x 792 ) / 792
= 1 / 792
= 1
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 981, 395, 792, 878 is 1
