Given numbers are 278, 123, 988, 443

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

Apply this formula for all numbers.

Step1:

LCM(278, 123) = 34194

GCD(278, 123) = ( 278 x 123 ) / 34194

= 278 / 123

= 278

Step2:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 278, 123, 988, 443 is 1
