GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 289) = 71961
GCD(249, 289) = ( 249 x 289 ) / 71961
= 249 / 289
= 249
Step2:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 249, 289, 955, 320 is 1
