Given numbers are 909, 843, 830, 990

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(909, 843) = 255429

GCD(909, 843) = ( 909 x 843 ) / 255429

= 909 / 843

= 909

Step2:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 909, 843, 830, 990 is 1
