Given numbers are 173, 648, 687, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 648) = 112104
GCD(173, 648) = ( 173 x 648 ) / 112104
= 173 / 648
= 173
Step2:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 173, 648, 687, 487 is 1
