Given numbers are 420, 614, 245, 492

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 614 are 2 x 307

Prime factors of 245 are 5 x 7 x 7

Prime factors of 492 are 2 x 2 x 3 x 41

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

Given numbers are 420, 614, 245, 492

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

Apply this formula for all numbers.

Step1:

LCM(420, 614) = 128940

GCD(420, 614) = ( 420 x 614 ) / 128940

= 420 / 614

= 420

Step2:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

Step3:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

So, Greatest Common Divisor of 420, 614, 245, 492 is 1
