Given numbers are 490, 120, 242, 801

The list of prime factors of all numbers are

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

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 242 are 2 x 11 x 11

Prime factors of 801 are 3 x 3 x 89

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

Given numbers are 490, 120, 242, 801

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

Apply this formula for all numbers.

Step1:

LCM(490, 120) = 5880

GCD(490, 120) = ( 490 x 120 ) / 5880

= 490 / 120

= 490

Step2:

LCM(10, 242) = 1210

GCD(10, 242) = ( 10 x 242 ) / 1210

= 10 / 242

= 10

Step3:

LCM(2, 801) = 1602

GCD(2, 801) = ( 2 x 801 ) / 1602

= 2 / 801

= 2

So, Greatest Common Divisor of 490, 120, 242, 801 is 1
