Given numbers are 217, 781, 330, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 781) = 169477
GCD(217, 781) = ( 217 x 781 ) / 169477
= 217 / 781
= 217
Step2:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
Step3:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
So, Greatest Common Divisor of 217, 781, 330, 295 is 1
