Given numbers are 687, 461, 709, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 461) = 316707
GCD(687, 461) = ( 687 x 461 ) / 316707
= 687 / 461
= 687
Step2:
LCM(1, 709) = 709
GCD(1, 709) = ( 1 x 709 ) / 709
= 1 / 709
= 1
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 687, 461, 709, 665 is 1
