Given numbers are 990, 285, 890, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 285) = 18810
GCD(990, 285) = ( 990 x 285 ) / 18810
= 990 / 285
= 990
Step2:
LCM(15, 890) = 2670
GCD(15, 890) = ( 15 x 890 ) / 2670
= 15 / 890
= 15
Step3:
LCM(5, 511) = 2555
GCD(5, 511) = ( 5 x 511 ) / 2555
= 5 / 511
= 5
So, Greatest Common Divisor of 990, 285, 890, 511 is 1
