Given numbers are 252, 405, 651, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 405) = 11340
GCD(252, 405) = ( 252 x 405 ) / 11340
= 252 / 405
= 252
Step2:
LCM(9, 651) = 1953
GCD(9, 651) = ( 9 x 651 ) / 1953
= 9 / 651
= 9
Step3:
LCM(3, 405) = 405
GCD(3, 405) = ( 3 x 405 ) / 405
= 3 / 405
= 3
So, Greatest Common Divisor of 252, 405, 651, 405 is 3
