Given numbers are 278, 392, 805, 705

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

Apply this formula for all numbers.

Step1:

LCM(278, 392) = 54488

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

= 278 / 392

= 278

Step2:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 278, 392, 805, 705 is 1
