Given numbers are 393, 970, 258, 783

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

Apply this formula for all numbers.

Step1:

LCM(393, 970) = 381210

GCD(393, 970) = ( 393 x 970 ) / 381210

= 393 / 970

= 393

Step2:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

Step3:

LCM(1, 783) = 783

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

= 1 / 783

= 1

So, Greatest Common Divisor of 393, 970, 258, 783 is 1
