Given numbers are 645, 850, 848, 781

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

Prime factors of 781 are 11 x 71

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

Given numbers are 645, 850, 848, 781

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

Apply this formula for all numbers.

Step1:

LCM(645, 850) = 109650

GCD(645, 850) = ( 645 x 850 ) / 109650

= 645 / 850

= 645

Step2:

LCM(5, 848) = 4240

GCD(5, 848) = ( 5 x 848 ) / 4240

= 5 / 848

= 5

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 645, 850, 848, 781 is 1
