Given numbers are 980, 220, 831, 272
The list of prime factors of all numbers are
Prime factors of 980 are 2 x 2 x 5 x 7 x 7
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 831 are 3 x 277
Prime factors of 272 are 2 x 2 x 2 x 2 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 980, 220, 831, 272
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 220) = 10780
GCD(980, 220) = ( 980 x 220 ) / 10780
= 980 / 220
= 980
Step2:
LCM(20, 831) = 16620
GCD(20, 831) = ( 20 x 831 ) / 16620
= 20 / 831
= 20
Step3:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
So, Greatest Common Divisor of 980, 220, 831, 272 is 1
