Given numbers are 725, 840, 670, 671

The list of prime factors of all numbers are

Prime factors of 725 are 5 x 5 x 29

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 670 are 2 x 5 x 67

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 725, 840, 670, 671

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

Apply this formula for all numbers.

Step1:

LCM(725, 840) = 121800

GCD(725, 840) = ( 725 x 840 ) / 121800

= 725 / 840

= 725

Step2:

LCM(5, 670) = 670

GCD(5, 670) = ( 5 x 670 ) / 670

= 5 / 670

= 5

Step3:

LCM(5, 671) = 3355

GCD(5, 671) = ( 5 x 671 ) / 3355

= 5 / 671

= 5

So, Greatest Common Divisor of 725, 840, 670, 671 is 1
