Given numbers are 909, 345, 201, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 345) = 104535
GCD(909, 345) = ( 909 x 345 ) / 104535
= 909 / 345
= 909
Step2:
LCM(3, 201) = 201
GCD(3, 201) = ( 3 x 201 ) / 201
= 3 / 201
= 3
Step3:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
So, Greatest Common Divisor of 909, 345, 201, 865 is 1
