Given numbers are 378, 497, 245, 805

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

Apply this formula for all numbers.

Step1:

LCM(378, 497) = 26838

GCD(378, 497) = ( 378 x 497 ) / 26838

= 378 / 497

= 378

Step2:

LCM(7, 245) = 245

GCD(7, 245) = ( 7 x 245 ) / 245

= 7 / 245

= 7

Step3:

LCM(7, 805) = 805

GCD(7, 805) = ( 7 x 805 ) / 805

= 7 / 805

= 7

So, Greatest Common Divisor of 378, 497, 245, 805 is 7
