Given numbers are 828, 470, 745, 661

The list of prime factors of all numbers are

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 470 are 2 x 5 x 47

Prime factors of 745 are 5 x 149

Prime factors of 661 are 661

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

Given numbers are 828, 470, 745, 661

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

Apply this formula for all numbers.

Step1:

LCM(828, 470) = 194580

GCD(828, 470) = ( 828 x 470 ) / 194580

= 828 / 470

= 828

Step2:

LCM(2, 745) = 1490

GCD(2, 745) = ( 2 x 745 ) / 1490

= 2 / 745

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 828, 470, 745, 661 is 1
