Given numbers are 820, 930, 743, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 930) = 76260
GCD(820, 930) = ( 820 x 930 ) / 76260
= 820 / 930
= 820
Step2:
LCM(10, 743) = 7430
GCD(10, 743) = ( 10 x 743 ) / 7430
= 10 / 743
= 10
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 820, 930, 743, 815 is 1
