Given numbers are 980, 625, 490, 747

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 625 are 5 x 5 x 5 x 5

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

Prime factors of 747 are 3 x 3 x 83

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

Given numbers are 980, 625, 490, 747

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

Apply this formula for all numbers.

Step1:

LCM(980, 625) = 122500

GCD(980, 625) = ( 980 x 625 ) / 122500

= 980 / 625

= 980

Step2:

LCM(5, 490) = 490

GCD(5, 490) = ( 5 x 490 ) / 490

= 5 / 490

= 5

Step3:

LCM(5, 747) = 3735

GCD(5, 747) = ( 5 x 747 ) / 3735

= 5 / 747

= 5

So, Greatest Common Divisor of 980, 625, 490, 747 is 1
