Given numbers are 822, 821, 447, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 821) = 674862
GCD(822, 821) = ( 822 x 821 ) / 674862
= 822 / 821
= 822
Step2:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 822, 821, 447, 388 is 1
