Given numbers are 730, 855, 841, 780

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 841 are 29 x 29

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

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

Given numbers are 730, 855, 841, 780

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

Apply this formula for all numbers.

Step1:

LCM(730, 855) = 124830

GCD(730, 855) = ( 730 x 855 ) / 124830

= 730 / 855

= 730

Step2:

LCM(5, 841) = 4205

GCD(5, 841) = ( 5 x 841 ) / 4205

= 5 / 841

= 5

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 730, 855, 841, 780 is 1
