Given numbers are 455, 811, 249, 730
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 811) = 369005
GCD(455, 811) = ( 455 x 811 ) / 369005
= 455 / 811
= 455
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
So, Greatest Common Divisor of 455, 811, 249, 730 is 1
