Given numbers are 279, 354, 217, 638

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

Apply this formula for all numbers.

Step1:

LCM(279, 354) = 32922

GCD(279, 354) = ( 279 x 354 ) / 32922

= 279 / 354

= 279

Step2:

LCM(3, 217) = 651

GCD(3, 217) = ( 3 x 217 ) / 651

= 3 / 217

= 3

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 279, 354, 217, 638 is 1
