Given numbers are 391, 368, 921, 674

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

Apply this formula for all numbers.

Step1:

LCM(391, 368) = 6256

GCD(391, 368) = ( 391 x 368 ) / 6256

= 391 / 368

= 391

Step2:

LCM(23, 921) = 21183

GCD(23, 921) = ( 23 x 921 ) / 21183

= 23 / 921

= 23

Step3:

LCM(1, 674) = 674

GCD(1, 674) = ( 1 x 674 ) / 674

= 1 / 674

= 1

So, Greatest Common Divisor of 391, 368, 921, 674 is 1
