Given numbers are 473, 490, 390, 957

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

Apply this formula for all numbers.

Step1:

LCM(473, 490) = 231770

GCD(473, 490) = ( 473 x 490 ) / 231770

= 473 / 490

= 473

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 473, 490, 390, 957 is 1
