Given numbers are 278, 478, 636, 893

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

Apply this formula for all numbers.

Step1:

LCM(278, 478) = 66442

GCD(278, 478) = ( 278 x 478 ) / 66442

= 278 / 478

= 278

Step2:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

Step3:

LCM(2, 893) = 1786

GCD(2, 893) = ( 2 x 893 ) / 1786

= 2 / 893

= 2

So, Greatest Common Divisor of 278, 478, 636, 893 is 1
