GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 194) = 133278
GCD(687, 194) = ( 687 x 194 ) / 133278
= 687 / 194
= 687
Step2:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 687, 194, 862, 945 is 1
