Given numbers are 312, 481, 155, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 481) = 11544
GCD(312, 481) = ( 312 x 481 ) / 11544
= 312 / 481
= 312
Step2:
LCM(13, 155) = 2015
GCD(13, 155) = ( 13 x 155 ) / 2015
= 13 / 155
= 13
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 312, 481, 155, 215 is 1
