Given numbers are 140, 460, 212, 639

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 212 are 2 x 2 x 53

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 140, 460, 212, 639

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

Apply this formula for all numbers.

Step1:

LCM(140, 460) = 3220

GCD(140, 460) = ( 140 x 460 ) / 3220

= 140 / 460

= 140

Step2:

LCM(20, 212) = 1060

GCD(20, 212) = ( 20 x 212 ) / 1060

= 20 / 212

= 20

Step3:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

So, Greatest Common Divisor of 140, 460, 212, 639 is 1
