Given numbers are 685, 400, 722
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 400) = 54800
GCD(685, 400) = ( 685 x 400 ) / 54800
= 685 / 400
= 685
Step2:
LCM(5, 722) = 3610
GCD(5, 722) = ( 5 x 722 ) / 3610
= 5 / 722
= 5
So, Greatest Common Divisor of 685, 400, 722 is 1
