Given numbers are 685, 834, 514, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 834) = 571290
GCD(685, 834) = ( 685 x 834 ) / 571290
= 685 / 834
= 685
Step2:
LCM(1, 514) = 514
GCD(1, 514) = ( 1 x 514 ) / 514
= 1 / 514
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 685, 834, 514, 815 is 1
