Given numbers are 638, 363, 205, 564
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 363) = 21054
GCD(638, 363) = ( 638 x 363 ) / 21054
= 638 / 363
= 638
Step2:
LCM(11, 205) = 2255
GCD(11, 205) = ( 11 x 205 ) / 2255
= 11 / 205
= 11
Step3:
LCM(1, 564) = 564
GCD(1, 564) = ( 1 x 564 ) / 564
= 1 / 564
= 1
So, Greatest Common Divisor of 638, 363, 205, 564 is 1
