Given numbers are 390, 237, 830, 942

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

Apply this formula for all numbers.

Step1:

LCM(390, 237) = 30810

GCD(390, 237) = ( 390 x 237 ) / 30810

= 390 / 237

= 390

Step2:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

Step3:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

So, Greatest Common Divisor of 390, 237, 830, 942 is 1
