Given numbers are 220, 197, 420, 341
The list of prime factors of all numbers are
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 197 are 197
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 341 are 11 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 220, 197, 420, 341
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 197) = 43340
GCD(220, 197) = ( 220 x 197 ) / 43340
= 220 / 197
= 220
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 341) = 341
GCD(1, 341) = ( 1 x 341 ) / 341
= 1 / 341
= 1
So, Greatest Common Divisor of 220, 197, 420, 341 is 1
