Given numbers are 222, 840, 545, 665

The list of prime factors of all numbers are

Prime factors of 222 are 2 x 3 x 37

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 545 are 5 x 109

Prime factors of 665 are 5 x 7 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 222, 840, 545, 665

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

Apply this formula for all numbers.

Step1:

LCM(222, 840) = 31080

GCD(222, 840) = ( 222 x 840 ) / 31080

= 222 / 840

= 222

Step2:

LCM(6, 545) = 3270

GCD(6, 545) = ( 6 x 545 ) / 3270

= 6 / 545

= 6

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 222, 840, 545, 665 is 1
