Given numbers are 870, 562, 739, 643

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 562 are 2 x 281

Prime factors of 739 are 739

Prime factors of 643 are 643

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

Given numbers are 870, 562, 739, 643

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

Apply this formula for all numbers.

Step1:

LCM(870, 562) = 244470

GCD(870, 562) = ( 870 x 562 ) / 244470

= 870 / 562

= 870

Step2:

LCM(2, 739) = 1478

GCD(2, 739) = ( 2 x 739 ) / 1478

= 2 / 739

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 870, 562, 739, 643 is 1
