Given numbers are 621, 260, 247, 783

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 247 are 13 x 19

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 621, 260, 247, 783

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

Apply this formula for all numbers.

Step1:

LCM(621, 260) = 161460

GCD(621, 260) = ( 621 x 260 ) / 161460

= 621 / 260

= 621

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 621, 260, 247, 783 is 1
