Given numbers are 278, 658, 445, 823

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

Apply this formula for all numbers.

Step1:

LCM(278, 658) = 91462

GCD(278, 658) = ( 278 x 658 ) / 91462

= 278 / 658

= 278

Step2:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 278, 658, 445, 823 is 1
