Given numbers are 690, 691, 212, 146

The list of prime factors of all numbers are

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

Prime factors of 691 are 691

Prime factors of 212 are 2 x 2 x 53

Prime factors of 146 are 2 x 73

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

Given numbers are 690, 691, 212, 146

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

Apply this formula for all numbers.

Step1:

LCM(690, 691) = 476790

GCD(690, 691) = ( 690 x 691 ) / 476790

= 690 / 691

= 690

Step2:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 690, 691, 212, 146 is 1
