Given numbers are 221, 786, 546, 780

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 786 are 2 x 3 x 131

Prime factors of 546 are 2 x 3 x 7 x 13

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 221, 786, 546, 780

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

Apply this formula for all numbers.

Step1:

LCM(221, 786) = 173706

GCD(221, 786) = ( 221 x 786 ) / 173706

= 221 / 786

= 221

Step2:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 221, 786, 546, 780 is 1
