Given numbers are 781, 393, 612, 753

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

Apply this formula for all numbers.

Step1:

LCM(781, 393) = 306933

GCD(781, 393) = ( 781 x 393 ) / 306933

= 781 / 393

= 781

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 753) = 753

GCD(1, 753) = ( 1 x 753 ) / 753

= 1 / 753

= 1

So, Greatest Common Divisor of 781, 393, 612, 753 is 1
