Given numbers are 390, 978, 593, 842

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

Apply this formula for all numbers.

Step1:

LCM(390, 978) = 63570

GCD(390, 978) = ( 390 x 978 ) / 63570

= 390 / 978

= 390

Step2:

LCM(6, 593) = 3558

GCD(6, 593) = ( 6 x 593 ) / 3558

= 6 / 593

= 6

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 390, 978, 593, 842 is 1
