Given numbers are 166, 220, 105, 782

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

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

Prime factors of 105 are 3 x 5 x 7

Prime factors of 782 are 2 x 17 x 23

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

Given numbers are 166, 220, 105, 782

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

Apply this formula for all numbers.

Step1:

LCM(166, 220) = 18260

GCD(166, 220) = ( 166 x 220 ) / 18260

= 166 / 220

= 166

Step2:

LCM(2, 105) = 210

GCD(2, 105) = ( 2 x 105 ) / 210

= 2 / 105

= 2

Step3:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

So, Greatest Common Divisor of 166, 220, 105, 782 is 1
