Given numbers are 170, 986, 255, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 986) = 4930
GCD(170, 986) = ( 170 x 986 ) / 4930
= 170 / 986
= 170
Step2:
LCM(34, 255) = 510
GCD(34, 255) = ( 34 x 255 ) / 510
= 34 / 255
= 34
Step3:
LCM(17, 262) = 4454
GCD(17, 262) = ( 17 x 262 ) / 4454
= 17 / 262
= 17
So, Greatest Common Divisor of 170, 986, 255, 262 is 1
