Given numbers are 814, 419, 690, 490

The list of prime factors of all numbers are

Prime factors of 814 are 2 x 11 x 37

Prime factors of 419 are 419

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 814, 419, 690, 490

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

Apply this formula for all numbers.

Step1:

LCM(814, 419) = 341066

GCD(814, 419) = ( 814 x 419 ) / 341066

= 814 / 419

= 814

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 814, 419, 690, 490 is 1
