Given numbers are 690, 546, 627, 145

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 627 are 3 x 11 x 19

Prime factors of 145 are 5 x 29

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

Given numbers are 690, 546, 627, 145

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

Apply this formula for all numbers.

Step1:

LCM(690, 546) = 62790

GCD(690, 546) = ( 690 x 546 ) / 62790

= 690 / 546

= 690

Step2:

LCM(6, 627) = 1254

GCD(6, 627) = ( 6 x 627 ) / 1254

= 6 / 627

= 6

Step3:

LCM(3, 145) = 435

GCD(3, 145) = ( 3 x 145 ) / 435

= 3 / 145

= 3

So, Greatest Common Divisor of 690, 546, 627, 145 is 1
