Given numbers are 437, 209, 907, 391

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

Apply this formula for all numbers.

Step1:

LCM(437, 209) = 4807

GCD(437, 209) = ( 437 x 209 ) / 4807

= 437 / 209

= 437

Step2:

LCM(19, 907) = 17233

GCD(19, 907) = ( 19 x 907 ) / 17233

= 19 / 907

= 19

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 437, 209, 907, 391 is 1
