GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 621) = 47196
GCD(228, 621) = ( 228 x 621 ) / 47196
= 228 / 621
= 228
Step2:
LCM(3, 345) = 345
GCD(3, 345) = ( 3 x 345 ) / 345
= 3 / 345
= 3
Step3:
LCM(3, 909) = 909
GCD(3, 909) = ( 3 x 909 ) / 909
= 3 / 909
= 3
So, Greatest Common Divisor of 228, 621, 345, 909 is 3
