Given numbers are 340, 131, 253, 643
The list of prime factors of all numbers are
Prime factors of 340 are 2 x 2 x 5 x 17
Prime factors of 131 are 131
Prime factors of 253 are 11 x 23
Prime factors of 643 are 643
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 340, 131, 253, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 131) = 44540
GCD(340, 131) = ( 340 x 131 ) / 44540
= 340 / 131
= 340
Step2:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 340, 131, 253, 643 is 1
