Given numbers are 490, 636, 611, 783

The list of prime factors of all numbers are

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

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 611 are 13 x 47

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 490, 636, 611, 783

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

Apply this formula for all numbers.

Step1:

LCM(490, 636) = 155820

GCD(490, 636) = ( 490 x 636 ) / 155820

= 490 / 636

= 490

Step2:

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

= 2 / 611

= 2

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 490, 636, 611, 783 is 1
