Given numbers are 453, 408, 247, 909

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

Apply this formula for all numbers.

Step1:

LCM(453, 408) = 61608

GCD(453, 408) = ( 453 x 408 ) / 61608

= 453 / 408

= 453

Step2:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 453, 408, 247, 909 is 1
