Given numbers are 831, 704, 793, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 704) = 585024
GCD(831, 704) = ( 831 x 704 ) / 585024
= 831 / 704
= 831
Step2:
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
= 1 / 793
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 831, 704, 793, 687 is 1
