Given numbers are 680, 695, 359, 816
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 695) = 94520
GCD(680, 695) = ( 680 x 695 ) / 94520
= 680 / 695
= 680
Step2:
LCM(5, 359) = 1795
GCD(5, 359) = ( 5 x 359 ) / 1795
= 5 / 359
= 5
Step3:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
So, Greatest Common Divisor of 680, 695, 359, 816 is 1
