Given numbers are 220, 126, 784, 765

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 220, 126, 784, 765

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

Apply this formula for all numbers.

Step1:

LCM(220, 126) = 13860

GCD(220, 126) = ( 220 x 126 ) / 13860

= 220 / 126

= 220

Step2:

LCM(2, 784) = 784

GCD(2, 784) = ( 2 x 784 ) / 784

= 2 / 784

= 2

Step3:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

So, Greatest Common Divisor of 220, 126, 784, 765 is 1
