Given numbers are 650, 340, 685, 455

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

Apply this formula for all numbers.

Step1:

LCM(650, 340) = 22100

GCD(650, 340) = ( 650 x 340 ) / 22100

= 650 / 340

= 650

Step2:

LCM(10, 685) = 1370

GCD(10, 685) = ( 10 x 685 ) / 1370

= 10 / 685

= 10

Step3:

LCM(5, 455) = 455

GCD(5, 455) = ( 5 x 455 ) / 455

= 5 / 455

= 5

So, Greatest Common Divisor of 650, 340, 685, 455 is 5
