Given numbers are 770, 480, 203, 830

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 203 are 7 x 29

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 770, 480, 203, 830

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

Apply this formula for all numbers.

Step1:

LCM(770, 480) = 36960

GCD(770, 480) = ( 770 x 480 ) / 36960

= 770 / 480

= 770

Step2:

LCM(10, 203) = 2030

GCD(10, 203) = ( 10 x 203 ) / 2030

= 10 / 203

= 10

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 770, 480, 203, 830 is 1
