Given numbers are 643, 745, 850, 781

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 745 are 5 x 149

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

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 643, 745, 850, 781

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

Apply this formula for all numbers.

Step1:

LCM(643, 745) = 479035

GCD(643, 745) = ( 643 x 745 ) / 479035

= 643 / 745

= 643

Step2:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 643, 745, 850, 781 is 1
