Given numbers are 768, 822, 485, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 822) = 105216
GCD(768, 822) = ( 768 x 822 ) / 105216
= 768 / 822
= 768
Step2:
LCM(6, 485) = 2910
GCD(6, 485) = ( 6 x 485 ) / 2910
= 6 / 485
= 6
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 768, 822, 485, 820 is 1
