Given numbers are 428, 245, 700, 671

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 245 are 5 x 7 x 7

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 671 are 11 x 61

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

Given numbers are 428, 245, 700, 671

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

Apply this formula for all numbers.

Step1:

LCM(428, 245) = 104860

GCD(428, 245) = ( 428 x 245 ) / 104860

= 428 / 245

= 428

Step2:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 428, 245, 700, 671 is 1
