Given numbers are 665, 709, 809, 608
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 709) = 471485
GCD(665, 709) = ( 665 x 709 ) / 471485
= 665 / 709
= 665
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 608) = 608
GCD(1, 608) = ( 1 x 608 ) / 608
= 1 / 608
= 1
So, Greatest Common Divisor of 665, 709, 809, 608 is 1
