Given numbers are 845, 100, 243, 649

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

Apply this formula for all numbers.

Step1:

LCM(845, 100) = 16900

GCD(845, 100) = ( 845 x 100 ) / 16900

= 845 / 100

= 845

Step2:

LCM(5, 243) = 1215

GCD(5, 243) = ( 5 x 243 ) / 1215

= 5 / 243

= 5

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 845, 100, 243, 649 is 1
