Given numbers are 730, 750, 389, 821

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

Prime factors of 389 are 389

Prime factors of 821 are 821

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

Given numbers are 730, 750, 389, 821

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

Apply this formula for all numbers.

Step1:

LCM(730, 750) = 54750

GCD(730, 750) = ( 730 x 750 ) / 54750

= 730 / 750

= 730

Step2:

LCM(10, 389) = 3890

GCD(10, 389) = ( 10 x 389 ) / 3890

= 10 / 389

= 10

Step3:

LCM(1, 821) = 821

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

= 1 / 821

= 1

So, Greatest Common Divisor of 730, 750, 389, 821 is 1
