Given numbers are 249, 519, 124, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 519) = 43077
GCD(249, 519) = ( 249 x 519 ) / 43077
= 249 / 519
= 249
Step2:
LCM(3, 124) = 372
GCD(3, 124) = ( 3 x 124 ) / 372
= 3 / 124
= 3
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 249, 519, 124, 405 is 1
