Given numbers are 436, 781, 172, 105

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 781 are 11 x 71

Prime factors of 172 are 2 x 2 x 43

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 436, 781, 172, 105

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

Apply this formula for all numbers.

Step1:

LCM(436, 781) = 340516

GCD(436, 781) = ( 436 x 781 ) / 340516

= 436 / 781

= 436

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 436, 781, 172, 105 is 1
