GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 904) = 640936
GCD(709, 904) = ( 709 x 904 ) / 640936
= 709 / 904
= 709
Step2:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 709, 904, 857, 989 is 1
