Given numbers are 278, 661, 406

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

Apply this formula for all numbers.

Step1:

LCM(278, 661) = 183758

GCD(278, 661) = ( 278 x 661 ) / 183758

= 278 / 661

= 278

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 278, 661, 406 is 1
