Given numbers are 146, 180, 783, 639

The list of prime factors of all numbers are

Prime factors of 146 are 2 x 73

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 146, 180, 783, 639

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

Apply this formula for all numbers.

Step1:

LCM(146, 180) = 13140

GCD(146, 180) = ( 146 x 180 ) / 13140

= 146 / 180

= 146

Step2:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 146, 180, 783, 639 is 1
