Given numbers are 641, 690, 559, 448

The list of prime factors of all numbers are

Prime factors of 641 are 641

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

Prime factors of 559 are 13 x 43

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

Given numbers are 641, 690, 559, 448

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

Apply this formula for all numbers.

Step1:

LCM(641, 690) = 442290

GCD(641, 690) = ( 641 x 690 ) / 442290

= 641 / 690

= 641

Step2:

LCM(1, 559) = 559

GCD(1, 559) = ( 1 x 559 ) / 559

= 1 / 559

= 1

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 641, 690, 559, 448 is 1
