Given numbers are 649, 845, 998, 766
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 845) = 548405
GCD(649, 845) = ( 649 x 845 ) / 548405
= 649 / 845
= 649
Step2:
LCM(1, 998) = 998
GCD(1, 998) = ( 1 x 998 ) / 998
= 1 / 998
= 1
Step3:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
So, Greatest Common Divisor of 649, 845, 998, 766 is 1
