Given numbers are 670, 245, 562, 643

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 245 are 5 x 7 x 7

Prime factors of 562 are 2 x 281

Prime factors of 643 are 643

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

Given numbers are 670, 245, 562, 643

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

Apply this formula for all numbers.

Step1:

LCM(670, 245) = 32830

GCD(670, 245) = ( 670 x 245 ) / 32830

= 670 / 245

= 670

Step2:

LCM(5, 562) = 2810

GCD(5, 562) = ( 5 x 562 ) / 2810

= 5 / 562

= 5

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 670, 245, 562, 643 is 1
