Given numbers are 278, 731, 124, 487

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

Apply this formula for all numbers.

Step1:

LCM(278, 731) = 203218

GCD(278, 731) = ( 278 x 731 ) / 203218

= 278 / 731

= 278

Step2:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 278, 731, 124, 487 is 1
