Given numbers are 786, 231, 490, 661

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 231 are 3 x 7 x 11

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 661 are 661

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

Given numbers are 786, 231, 490, 661

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

Apply this formula for all numbers.

Step1:

LCM(786, 231) = 60522

GCD(786, 231) = ( 786 x 231 ) / 60522

= 786 / 231

= 786

Step2:

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

= 3 / 490

= 3

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 786, 231, 490, 661 is 1
