Given numbers are 820, 980, 347

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 347 are 347

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

Given numbers are 820, 980, 347

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

Apply this formula for all numbers.

Step1:

LCM(820, 980) = 40180

GCD(820, 980) = ( 820 x 980 ) / 40180

= 820 / 980

= 820

Step2:

LCM(20, 347) = 6940

GCD(20, 347) = ( 20 x 347 ) / 6940

= 20 / 347

= 20

So, Greatest Common Divisor of 820, 980, 347 is 1
