Given numbers are 494, 458, 695, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 458) = 113126
GCD(494, 458) = ( 494 x 458 ) / 113126
= 494 / 458
= 494
Step2:
LCM(2, 695) = 1390
GCD(2, 695) = ( 2 x 695 ) / 1390
= 2 / 695
= 2
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 494, 458, 695, 809 is 1
