Given numbers are 785, 670, 280, 538

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 670 are 2 x 5 x 67

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 538 are 2 x 269

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

Given numbers are 785, 670, 280, 538

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

Apply this formula for all numbers.

Step1:

LCM(785, 670) = 105190

GCD(785, 670) = ( 785 x 670 ) / 105190

= 785 / 670

= 785

Step2:

LCM(5, 280) = 280

GCD(5, 280) = ( 5 x 280 ) / 280

= 5 / 280

= 5

Step3:

LCM(5, 538) = 2690

GCD(5, 538) = ( 5 x 538 ) / 2690

= 5 / 538

= 5

So, Greatest Common Divisor of 785, 670, 280, 538 is 1
