Given numbers are 392, 278, 40, 419

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

Apply this formula for all numbers.

Step1:

LCM(392, 278) = 54488

GCD(392, 278) = ( 392 x 278 ) / 54488

= 392 / 278

= 392

Step2:

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

= 2 / 40

= 2

Step3:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

So, Greatest Common Divisor of 392, 278, 40, 419 is 1
