Given numbers are 819, 602, 445, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 602) = 70434
GCD(819, 602) = ( 819 x 602 ) / 70434
= 819 / 602
= 819
Step2:
LCM(7, 445) = 3115
GCD(7, 445) = ( 7 x 445 ) / 3115
= 7 / 445
= 7
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 819, 602, 445, 215 is 1
