Given numbers are 202, 310, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(202, 310) = 31310
GCD(202, 310) = ( 202 x 310 ) / 31310
= 202 / 310
= 202
Step2:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
So, Greatest Common Divisor of 202, 310, 405 is 1
