Given numbers are 644, 343, 397, 267

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

Apply this formula for all numbers.

Step1:

LCM(644, 343) = 31556

GCD(644, 343) = ( 644 x 343 ) / 31556

= 644 / 343

= 644

Step2:

LCM(7, 397) = 2779

GCD(7, 397) = ( 7 x 397 ) / 2779

= 7 / 397

= 7

Step3:

LCM(1, 267) = 267

GCD(1, 267) = ( 1 x 267 ) / 267

= 1 / 267

= 1

So, Greatest Common Divisor of 644, 343, 397, 267 is 1
