Given numbers are 561, 740, 370, 842

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 370 are 2 x 5 x 37

Prime factors of 842 are 2 x 421

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

Given numbers are 561, 740, 370, 842

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

Apply this formula for all numbers.

Step1:

LCM(561, 740) = 415140

GCD(561, 740) = ( 561 x 740 ) / 415140

= 561 / 740

= 561

Step2:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 561, 740, 370, 842 is 1
