Given numbers are 687, 303, 394, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 303) = 69387
GCD(687, 303) = ( 687 x 303 ) / 69387
= 687 / 303
= 687
Step2:
LCM(3, 394) = 1182
GCD(3, 394) = ( 3 x 394 ) / 1182
= 3 / 394
= 3
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 687, 303, 394, 159 is 1
