Given numbers are 313, 487, 685, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(313, 487) = 152431
GCD(313, 487) = ( 313 x 487 ) / 152431
= 313 / 487
= 313
Step2:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
Step3:
LCM(1, 255) = 255
GCD(1, 255) = ( 1 x 255 ) / 255
= 1 / 255
= 1
So, Greatest Common Divisor of 313, 487, 685, 255 is 1
