Given numbers are 381, 390, 822, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 390) = 49530
GCD(381, 390) = ( 381 x 390 ) / 49530
= 381 / 390
= 381
Step2:
LCM(3, 822) = 822
GCD(3, 822) = ( 3 x 822 ) / 822
= 3 / 822
= 3
Step3:
LCM(3, 203) = 609
GCD(3, 203) = ( 3 x 203 ) / 609
= 3 / 203
= 3
So, Greatest Common Divisor of 381, 390, 822, 203 is 1
