Given numbers are 660, 225, 862, 772

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Prime factors of 862 are 2 x 431

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 660, 225, 862, 772

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

Apply this formula for all numbers.

Step1:

LCM(660, 225) = 9900

GCD(660, 225) = ( 660 x 225 ) / 9900

= 660 / 225

= 660

Step2:

LCM(15, 862) = 12930

GCD(15, 862) = ( 15 x 862 ) / 12930

= 15 / 862

= 15

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 660, 225, 862, 772 is 1
