Given numbers are 610, 395, 278, 658

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

Prime factors of 395 are 5 x 79

Prime factors of 278 are 2 x 139

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 610, 395, 278, 658

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

Apply this formula for all numbers.

Step1:

LCM(610, 395) = 48190

GCD(610, 395) = ( 610 x 395 ) / 48190

= 610 / 395

= 610

Step2:

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

= 5 / 278

= 5

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 610, 395, 278, 658 is 1
