Given numbers are 670, 530, 320, 398

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

Apply this formula for all numbers.

Step1:

LCM(670, 530) = 35510

GCD(670, 530) = ( 670 x 530 ) / 35510

= 670 / 530

= 670

Step2:

LCM(10, 320) = 320

GCD(10, 320) = ( 10 x 320 ) / 320

= 10 / 320

= 10

Step3:

LCM(10, 398) = 1990

GCD(10, 398) = ( 10 x 398 ) / 1990

= 10 / 398

= 10

So, Greatest Common Divisor of 670, 530, 320, 398 is 2
