Given numbers are 822, 123, 580, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 123) = 33702
GCD(822, 123) = ( 822 x 123 ) / 33702
= 822 / 123
= 822
Step2:
LCM(3, 580) = 1740
GCD(3, 580) = ( 3 x 580 ) / 1740
= 3 / 580
= 3
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 822, 123, 580, 644 is 1
