Given numbers are 687, 477, 864, 319
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 477) = 109233
GCD(687, 477) = ( 687 x 477 ) / 109233
= 687 / 477
= 687
Step2:
LCM(3, 864) = 864
GCD(3, 864) = ( 3 x 864 ) / 864
= 3 / 864
= 3
Step3:
LCM(3, 319) = 957
GCD(3, 319) = ( 3 x 319 ) / 957
= 3 / 319
= 3
So, Greatest Common Divisor of 687, 477, 864, 319 is 1
