Given numbers are 223, 420, 768, 658

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

Apply this formula for all numbers.

Step1:

LCM(223, 420) = 93660

GCD(223, 420) = ( 223 x 420 ) / 93660

= 223 / 420

= 223

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 223, 420, 768, 658 is 1
