Given numbers are 408, 110, 990, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 110) = 22440
GCD(408, 110) = ( 408 x 110 ) / 22440
= 408 / 110
= 408
Step2:
LCM(2, 990) = 990
GCD(2, 990) = ( 2 x 990 ) / 990
= 2 / 990
= 2
Step3:
LCM(2, 813) = 1626
GCD(2, 813) = ( 2 x 813 ) / 1626
= 2 / 813
= 2
So, Greatest Common Divisor of 408, 110, 990, 813 is 1
