Given numbers are 215, 310, 168, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 310) = 13330
GCD(215, 310) = ( 215 x 310 ) / 13330
= 215 / 310
= 215
Step2:
LCM(5, 168) = 840
GCD(5, 168) = ( 5 x 168 ) / 840
= 5 / 168
= 5
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 215, 310, 168, 905 is 1
