Given numbers are 705, 279, 642, 224

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

Apply this formula for all numbers.

Step1:

LCM(705, 279) = 65565

GCD(705, 279) = ( 705 x 279 ) / 65565

= 705 / 279

= 705

Step2:

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

= 3 / 642

= 3

Step3:

LCM(3, 224) = 672

GCD(3, 224) = ( 3 x 224 ) / 672

= 3 / 224

= 3

So, Greatest Common Divisor of 705, 279, 642, 224 is 1
