Given numbers are 585, 306, 638, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(585, 306) = 19890
GCD(585, 306) = ( 585 x 306 ) / 19890
= 585 / 306
= 585
Step2:
LCM(9, 638) = 5742
GCD(9, 638) = ( 9 x 638 ) / 5742
= 9 / 638
= 9
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 585, 306, 638, 521 is 1
