Given numbers are 225, 723, 644, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 723) = 54225
GCD(225, 723) = ( 225 x 723 ) / 54225
= 225 / 723
= 225
Step2:
LCM(3, 644) = 1932
GCD(3, 644) = ( 3 x 644 ) / 1932
= 3 / 644
= 3
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 225, 723, 644, 663 is 1
