GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 790) = 324690
GCD(822, 790) = ( 822 x 790 ) / 324690
= 822 / 790
= 822
Step2:
LCM(2, 629) = 1258
GCD(2, 629) = ( 2 x 629 ) / 1258
= 2 / 629
= 2
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 822, 790, 629, 561 is 1
