Given numbers are 660, 415, 690, 213

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 415 are 5 x 83

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

Prime factors of 213 are 3 x 71

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

Given numbers are 660, 415, 690, 213

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

Apply this formula for all numbers.

Step1:

LCM(660, 415) = 54780

GCD(660, 415) = ( 660 x 415 ) / 54780

= 660 / 415

= 660

Step2:

LCM(5, 690) = 690

GCD(5, 690) = ( 5 x 690 ) / 690

= 5 / 690

= 5

Step3:

LCM(5, 213) = 1065

GCD(5, 213) = ( 5 x 213 ) / 1065

= 5 / 213

= 5

So, Greatest Common Divisor of 660, 415, 690, 213 is 1
