Given numbers are 646, 361, 966, 907

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

Apply this formula for all numbers.

Step1:

LCM(646, 361) = 12274

GCD(646, 361) = ( 646 x 361 ) / 12274

= 646 / 361

= 646

Step2:

LCM(19, 966) = 18354

GCD(19, 966) = ( 19 x 966 ) / 18354

= 19 / 966

= 19

Step3:

LCM(1, 907) = 907

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

= 1 / 907

= 1

So, Greatest Common Divisor of 646, 361, 966, 907 is 1
