Given numbers are 870, 706, 163, 619

The list of prime factors of all numbers are

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

Prime factors of 706 are 2 x 353

Prime factors of 163 are 163

Prime factors of 619 are 619

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

Given numbers are 870, 706, 163, 619

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

Apply this formula for all numbers.

Step1:

LCM(870, 706) = 307110

GCD(870, 706) = ( 870 x 706 ) / 307110

= 870 / 706

= 870

Step2:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 870, 706, 163, 619 is 1
