Given numbers are 445, 390, 940, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 390) = 34710
GCD(445, 390) = ( 445 x 390 ) / 34710
= 445 / 390
= 445
Step2:
LCM(5, 940) = 940
GCD(5, 940) = ( 5 x 940 ) / 940
= 5 / 940
= 5
Step3:
LCM(5, 217) = 1085
GCD(5, 217) = ( 5 x 217 ) / 1085
= 5 / 217
= 5
So, Greatest Common Divisor of 445, 390, 940, 217 is 1
