Given numbers are 222, 546, 453, 420

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

Apply this formula for all numbers.

Step1:

LCM(222, 546) = 20202

GCD(222, 546) = ( 222 x 546 ) / 20202

= 222 / 546

= 222

Step2:

LCM(6, 453) = 906

GCD(6, 453) = ( 6 x 453 ) / 906

= 6 / 453

= 6

Step3:

LCM(3, 420) = 420

GCD(3, 420) = ( 3 x 420 ) / 420

= 3 / 420

= 3

So, Greatest Common Divisor of 222, 546, 453, 420 is 3
