Given numbers are 820, 865, 472, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 865) = 141860
GCD(820, 865) = ( 820 x 865 ) / 141860
= 820 / 865
= 820
Step2:
LCM(5, 472) = 2360
GCD(5, 472) = ( 5 x 472 ) / 2360
= 5 / 472
= 5
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 820, 865, 472, 861 is 1
