Given numbers are 685, 747, 278

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

Apply this formula for all numbers.

Step1:

LCM(685, 747) = 511695

GCD(685, 747) = ( 685 x 747 ) / 511695

= 685 / 747

= 685

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 685, 747, 278 is 1
