Given numbers are 686, 441, 620, 907

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

Apply this formula for all numbers.

Step1:

LCM(686, 441) = 6174

GCD(686, 441) = ( 686 x 441 ) / 6174

= 686 / 441

= 686

Step2:

LCM(49, 620) = 30380

GCD(49, 620) = ( 49 x 620 ) / 30380

= 49 / 620

= 49

Step3:

LCM(1, 907) = 907

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

= 1 / 907

= 1

So, Greatest Common Divisor of 686, 441, 620, 907 is 1
