Given numbers are 670, 730, 378, 238

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

Apply this formula for all numbers.

Step1:

LCM(670, 730) = 48910

GCD(670, 730) = ( 670 x 730 ) / 48910

= 670 / 730

= 670

Step2:

LCM(10, 378) = 1890

GCD(10, 378) = ( 10 x 378 ) / 1890

= 10 / 378

= 10

Step3:

LCM(2, 238) = 238

GCD(2, 238) = ( 2 x 238 ) / 238

= 2 / 238

= 2

So, Greatest Common Divisor of 670, 730, 378, 238 is 2
