Given numbers are 818, 890, 649, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 890) = 364010
GCD(818, 890) = ( 818 x 890 ) / 364010
= 818 / 890
= 818
Step2:
LCM(2, 649) = 1298
GCD(2, 649) = ( 2 x 649 ) / 1298
= 2 / 649
= 2
Step3:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
So, Greatest Common Divisor of 818, 890, 649, 422 is 1
