Given numbers are 249, 702, 654, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 702) = 58266
GCD(249, 702) = ( 249 x 702 ) / 58266
= 249 / 702
= 249
Step2:
LCM(3, 654) = 654
GCD(3, 654) = ( 3 x 654 ) / 654
= 3 / 654
= 3
Step3:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
So, Greatest Common Divisor of 249, 702, 654, 809 is 1
