Given numbers are 612, 840, 807, 355

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Prime factors of 807 are 3 x 269

Prime factors of 355 are 5 x 71

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

Given numbers are 612, 840, 807, 355

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

Apply this formula for all numbers.

Step1:

LCM(612, 840) = 42840

GCD(612, 840) = ( 612 x 840 ) / 42840

= 612 / 840

= 612

Step2:

LCM(12, 807) = 3228

GCD(12, 807) = ( 12 x 807 ) / 3228

= 12 / 807

= 12

Step3:

LCM(3, 355) = 1065

GCD(3, 355) = ( 3 x 355 ) / 1065

= 3 / 355

= 3

So, Greatest Common Divisor of 612, 840, 807, 355 is 1
