Given numbers are 623, 479, 519, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 479) = 298417
GCD(623, 479) = ( 623 x 479 ) / 298417
= 623 / 479
= 623
Step2:
LCM(1, 519) = 519
GCD(1, 519) = ( 1 x 519 ) / 519
= 1 / 519
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 623, 479, 519, 420 is 1
