Given numbers are 252, 225, 660, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 225) = 6300
GCD(252, 225) = ( 252 x 225 ) / 6300
= 252 / 225
= 252
Step2:
LCM(9, 660) = 1980
GCD(9, 660) = ( 9 x 660 ) / 1980
= 9 / 660
= 9
Step3:
LCM(3, 423) = 423
GCD(3, 423) = ( 3 x 423 ) / 423
= 3 / 423
= 3
So, Greatest Common Divisor of 252, 225, 660, 423 is 3
