Given numbers are 905, 688, 578

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(905, 688) = 622640

GCD(905, 688) = ( 905 x 688 ) / 622640

= 905 / 688

= 905

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 905, 688, 578 is 1
