Given numbers are 690, 210, 964, 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 210 are 2 x 3 x 5 x 7

Prime factors of 964 are 2 x 2 x 241

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, 210, 964, 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, 210) = 4830

GCD(690, 210) = ( 690 x 210 ) / 4830

= 690 / 210

= 690

Step2:

LCM(30, 964) = 14460

GCD(30, 964) = ( 30 x 964 ) / 14460

= 30 / 964

= 30

Step3:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

So, Greatest Common Divisor of 690, 210, 964, 145 is 1
