Given numbers are 458, 780, 885, 408
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 780) = 178620
GCD(458, 780) = ( 458 x 780 ) / 178620
= 458 / 780
= 458
Step2:
LCM(2, 885) = 1770
GCD(2, 885) = ( 2 x 885 ) / 1770
= 2 / 885
= 2
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 458, 780, 885, 408 is 1
