Given numbers are 134, 235, 221, 420
The list of prime factors of all numbers are
Prime factors of 134 are 2 x 67
Prime factors of 235 are 5 x 47
Prime factors of 221 are 13 x 17
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 134, 235, 221, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(134, 235) = 31490
GCD(134, 235) = ( 134 x 235 ) / 31490
= 134 / 235
= 134
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 134, 235, 221, 420 is 1
