Given numbers are 561, 213, 662, 377

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 213 are 3 x 71

Prime factors of 662 are 2 x 331

Prime factors of 377 are 13 x 29

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

Given numbers are 561, 213, 662, 377

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

Apply this formula for all numbers.

Step1:

LCM(561, 213) = 39831

GCD(561, 213) = ( 561 x 213 ) / 39831

= 561 / 213

= 561

Step2:

LCM(3, 662) = 1986

GCD(3, 662) = ( 3 x 662 ) / 1986

= 3 / 662

= 3

Step3:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

So, Greatest Common Divisor of 561, 213, 662, 377 is 1
