Given numbers are 705, 245, 808, 907

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

Apply this formula for all numbers.

Step1:

LCM(705, 245) = 34545

GCD(705, 245) = ( 705 x 245 ) / 34545

= 705 / 245

= 705

Step2:

LCM(5, 808) = 4040

GCD(5, 808) = ( 5 x 808 ) / 4040

= 5 / 808

= 5

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 705, 245, 808, 907 is 1
