Given numbers are 515, 420, 470, 225
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 420) = 43260
GCD(515, 420) = ( 515 x 420 ) / 43260
= 515 / 420
= 515
Step2:
LCM(5, 470) = 470
GCD(5, 470) = ( 5 x 470 ) / 470
= 5 / 470
= 5
Step3:
LCM(5, 225) = 225
GCD(5, 225) = ( 5 x 225 ) / 225
= 5 / 225
= 5
So, Greatest Common Divisor of 515, 420, 470, 225 is 5
