Given numbers are 421, 670, 278, 194

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

Apply this formula for all numbers.

Step1:

LCM(421, 670) = 282070

GCD(421, 670) = ( 421 x 670 ) / 282070

= 421 / 670

= 421

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 421, 670, 278, 194 is 1
