Given numbers are 265, 109, 986, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(265, 109) = 28885
GCD(265, 109) = ( 265 x 109 ) / 28885
= 265 / 109
= 265
Step2:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 265, 109, 986, 257 is 1
