Given numbers are 648, 980, 225, 770

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 648, 980, 225, 770

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

Apply this formula for all numbers.

Step1:

LCM(648, 980) = 158760

GCD(648, 980) = ( 648 x 980 ) / 158760

= 648 / 980

= 648

Step2:

LCM(4, 225) = 900

GCD(4, 225) = ( 4 x 225 ) / 900

= 4 / 225

= 4

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 648, 980, 225, 770 is 1
