Given numbers are 820, 235, 909, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 235) = 38540
GCD(820, 235) = ( 820 x 235 ) / 38540
= 820 / 235
= 820
Step2:
LCM(5, 909) = 4545
GCD(5, 909) = ( 5 x 909 ) / 4545
= 5 / 909
= 5
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 820, 235, 909, 694 is 1
