Given numbers are 378, 249, 805, 222

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

Apply this formula for all numbers.

Step1:

LCM(378, 249) = 31374

GCD(378, 249) = ( 378 x 249 ) / 31374

= 378 / 249

= 378

Step2:

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

= 3 / 805

= 3

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 378, 249, 805, 222 is 1
