Given numbers are 843, 560, 644, 553

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 553 are 7 x 79

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

Given numbers are 843, 560, 644, 553

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

Apply this formula for all numbers.

Step1:

LCM(843, 560) = 472080

GCD(843, 560) = ( 843 x 560 ) / 472080

= 843 / 560

= 843

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 843, 560, 644, 553 is 1
