Given numbers are 687, 660, 933, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 660) = 151140
GCD(687, 660) = ( 687 x 660 ) / 151140
= 687 / 660
= 687
Step2:
LCM(3, 933) = 933
GCD(3, 933) = ( 3 x 933 ) / 933
= 3 / 933
= 3
Step3:
LCM(3, 478) = 1434
GCD(3, 478) = ( 3 x 478 ) / 1434
= 3 / 478
= 3
So, Greatest Common Divisor of 687, 660, 933, 478 is 1
