Given numbers are 647, 198, 950, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 198) = 128106
GCD(647, 198) = ( 647 x 198 ) / 128106
= 647 / 198
= 647
Step2:
LCM(1, 950) = 950
GCD(1, 950) = ( 1 x 950 ) / 950
= 1 / 950
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 647, 198, 950, 789 is 1
