Given numbers are 453, 172, 780, 822

The list of prime factors of all numbers are

Prime factors of 453 are 3 x 151

Prime factors of 172 are 2 x 2 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 453, 172, 780, 822

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

Apply this formula for all numbers.

Step1:

LCM(453, 172) = 77916

GCD(453, 172) = ( 453 x 172 ) / 77916

= 453 / 172

= 453

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 453, 172, 780, 822 is 1
