Given numbers are 124, 520, 424, 278

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

Apply this formula for all numbers.

Step1:

LCM(124, 520) = 16120

GCD(124, 520) = ( 124 x 520 ) / 16120

= 124 / 520

= 124

Step2:

LCM(4, 424) = 424

GCD(4, 424) = ( 4 x 424 ) / 424

= 4 / 424

= 4

Step3:

LCM(4, 278) = 556

GCD(4, 278) = ( 4 x 278 ) / 556

= 4 / 278

= 4

So, Greatest Common Divisor of 124, 520, 424, 278 is 2
