Given numbers are 810, 440, 780, 582
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 440) = 35640
GCD(810, 440) = ( 810 x 440 ) / 35640
= 810 / 440
= 810
Step2:
LCM(10, 780) = 780
GCD(10, 780) = ( 10 x 780 ) / 780
= 10 / 780
= 10
Step3:
LCM(10, 582) = 2910
GCD(10, 582) = ( 10 x 582 ) / 2910
= 10 / 582
= 10
So, Greatest Common Divisor of 810, 440, 780, 582 is 2
