Given numbers are 235, 390, 263, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(235, 390) = 18330
GCD(235, 390) = ( 235 x 390 ) / 18330
= 235 / 390
= 235
Step2:
LCM(5, 263) = 1315
GCD(5, 263) = ( 5 x 263 ) / 1315
= 5 / 263
= 5
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 235, 390, 263, 845 is 1
