Given numbers are 710, 781, 244, 649

The list of prime factors of all numbers are

Prime factors of 710 are 2 x 5 x 71

Prime factors of 781 are 11 x 71

Prime factors of 244 are 2 x 2 x 61

Prime factors of 649 are 11 x 59

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

Given numbers are 710, 781, 244, 649

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

Apply this formula for all numbers.

Step1:

LCM(710, 781) = 7810

GCD(710, 781) = ( 710 x 781 ) / 7810

= 710 / 781

= 710

Step2:

LCM(71, 244) = 17324

GCD(71, 244) = ( 71 x 244 ) / 17324

= 71 / 244

= 71

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 710, 781, 244, 649 is 1
