Given numbers are 425, 720, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 720) = 61200
GCD(425, 720) = ( 425 x 720 ) / 61200
= 425 / 720
= 425
Step2:
LCM(5, 231) = 1155
GCD(5, 231) = ( 5 x 231 ) / 1155
= 5 / 231
= 5
So, Greatest Common Divisor of 425, 720, 231 is 1
