Given numbers are 217, 315, 791, 473
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 315) = 9765
GCD(217, 315) = ( 217 x 315 ) / 9765
= 217 / 315
= 217
Step2:
LCM(7, 791) = 791
GCD(7, 791) = ( 7 x 791 ) / 791
= 7 / 791
= 7
Step3:
LCM(7, 473) = 3311
GCD(7, 473) = ( 7 x 473 ) / 3311
= 7 / 473
= 7
So, Greatest Common Divisor of 217, 315, 791, 473 is 1
