Given numbers are 123, 219, 15, 496
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 219) = 8979
GCD(123, 219) = ( 123 x 219 ) / 8979
= 123 / 219
= 123
Step2:
LCM(3, 15) = 15
GCD(3, 15) = ( 3 x 15 ) / 15
= 3 / 15
= 3
Step3:
LCM(3, 496) = 1488
GCD(3, 496) = ( 3 x 496 ) / 1488
= 3 / 496
= 3
So, Greatest Common Divisor of 123, 219, 15, 496 is 1
