Given numbers are 394, 671, 783, 690

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

Apply this formula for all numbers.

Step1:

LCM(394, 671) = 264374

GCD(394, 671) = ( 394 x 671 ) / 264374

= 394 / 671

= 394

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 394, 671, 783, 690 is 1
