Given numbers are 170, 398, 755, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 398) = 33830
GCD(170, 398) = ( 170 x 398 ) / 33830
= 170 / 398
= 170
Step2:
LCM(2, 755) = 1510
GCD(2, 755) = ( 2 x 755 ) / 1510
= 2 / 755
= 2
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 170, 398, 755, 217 is 1
