Given numbers are 458, 540, 279, 225
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 540) = 123660
GCD(458, 540) = ( 458 x 540 ) / 123660
= 458 / 540
= 458
Step2:
LCM(2, 279) = 558
GCD(2, 279) = ( 2 x 279 ) / 558
= 2 / 279
= 2
Step3:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
So, Greatest Common Divisor of 458, 540, 279, 225 is 1
