Given numbers are 405, 380, 243, 533
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 380) = 30780
GCD(405, 380) = ( 405 x 380 ) / 30780
= 405 / 380
= 405
Step2:
LCM(5, 243) = 1215
GCD(5, 243) = ( 5 x 243 ) / 1215
= 5 / 243
= 5
Step3:
LCM(1, 533) = 533
GCD(1, 533) = ( 1 x 533 ) / 533
= 1 / 533
= 1
So, Greatest Common Divisor of 405, 380, 243, 533 is 1
