Given numbers are 109, 251, 409, 124

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

Apply this formula for all numbers.

Step1:

LCM(109, 251) = 27359

GCD(109, 251) = ( 109 x 251 ) / 27359

= 109 / 251

= 109

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 124) = 124

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

= 1 / 124

= 1

So, Greatest Common Divisor of 109, 251, 409, 124 is 1
