Given numbers are 672, 945, 749, 195

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

Apply this formula for all numbers.

Step1:

LCM(672, 945) = 30240

GCD(672, 945) = ( 672 x 945 ) / 30240

= 672 / 945

= 672

Step2:

LCM(21, 749) = 2247

GCD(21, 749) = ( 21 x 749 ) / 2247

= 21 / 749

= 21

Step3:

LCM(7, 195) = 1365

GCD(7, 195) = ( 7 x 195 ) / 1365

= 7 / 195

= 7

So, Greatest Common Divisor of 672, 945, 749, 195 is 1
