Given numbers are 822, 310, 123, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 310) = 127410
GCD(822, 310) = ( 822 x 310 ) / 127410
= 822 / 310
= 822
Step2:
LCM(2, 123) = 246
GCD(2, 123) = ( 2 x 123 ) / 246
= 2 / 123
= 2
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 822, 310, 123, 120 is 1
