Given numbers are 420, 449, 519, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 449) = 188580
GCD(420, 449) = ( 420 x 449 ) / 188580
= 420 / 449
= 420
Step2:
LCM(1, 519) = 519
GCD(1, 519) = ( 1 x 519 ) / 519
= 1 / 519
= 1
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 420, 449, 519, 456 is 1
