Given numbers are 454, 705, 821, 105

The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 705 are 3 x 5 x 47

Prime factors of 821 are 821

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 454, 705, 821, 105

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

Apply this formula for all numbers.

Step1:

LCM(454, 705) = 320070

GCD(454, 705) = ( 454 x 705 ) / 320070

= 454 / 705

= 454

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 105) = 105

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

= 1 / 105

= 1

So, Greatest Common Divisor of 454, 705, 821, 105 is 1
