Given numbers are 550, 845, 789, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 845) = 92950
GCD(550, 845) = ( 550 x 845 ) / 92950
= 550 / 845
= 550
Step2:
LCM(5, 789) = 3945
GCD(5, 789) = ( 5 x 789 ) / 3945
= 5 / 789
= 5
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 550, 845, 789, 142 is 1
