Given numbers are 780, 670, 298, 203

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 670 are 2 x 5 x 67

Prime factors of 298 are 2 x 149

Prime factors of 203 are 7 x 29

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

Given numbers are 780, 670, 298, 203

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

Apply this formula for all numbers.

Step1:

LCM(780, 670) = 52260

GCD(780, 670) = ( 780 x 670 ) / 52260

= 780 / 670

= 780

Step2:

LCM(10, 298) = 1490

GCD(10, 298) = ( 10 x 298 ) / 1490

= 10 / 298

= 10

Step3:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

So, Greatest Common Divisor of 780, 670, 298, 203 is 1
