Given numbers are 470, 784, 398, 487

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

Apply this formula for all numbers.

Step1:

LCM(470, 784) = 184240

GCD(470, 784) = ( 470 x 784 ) / 184240

= 470 / 784

= 470

Step2:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

Step3:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

So, Greatest Common Divisor of 470, 784, 398, 487 is 1
