GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 162) = 4050
GCD(225, 162) = ( 225 x 162 ) / 4050
= 225 / 162
= 225
Step2:
LCM(9, 651) = 1953
GCD(9, 651) = ( 9 x 651 ) / 1953
= 9 / 651
= 9
Step3:
LCM(3, 649) = 1947
GCD(3, 649) = ( 3 x 649 ) / 1947
= 3 / 649
= 3
So, Greatest Common Divisor of 225, 162, 651, 649 is 1
