Given numbers are 450, 390, 979, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 390) = 5850
GCD(450, 390) = ( 450 x 390 ) / 5850
= 450 / 390
= 450
Step2:
LCM(30, 979) = 29370
GCD(30, 979) = ( 30 x 979 ) / 29370
= 30 / 979
= 30
Step3:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
So, Greatest Common Divisor of 450, 390, 979, 205 is 1
