Given numbers are 571, 354, 780, 641

The list of prime factors of all numbers are

Prime factors of 571 are 571

Prime factors of 354 are 2 x 3 x 59

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 641 are 641

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

Given numbers are 571, 354, 780, 641

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

Apply this formula for all numbers.

Step1:

LCM(571, 354) = 202134

GCD(571, 354) = ( 571 x 354 ) / 202134

= 571 / 354

= 571

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 571, 354, 780, 641 is 1
