Given numbers are 458, 290, 403, 425
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 290) = 66410
GCD(458, 290) = ( 458 x 290 ) / 66410
= 458 / 290
= 458
Step2:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
Step3:
LCM(1, 425) = 425
GCD(1, 425) = ( 1 x 425 ) / 425
= 1 / 425
= 1
So, Greatest Common Divisor of 458, 290, 403, 425 is 1
