Given numbers are 340, 715, 517, 656
The list of prime factors of all numbers are
Prime factors of 340 are 2 x 2 x 5 x 17
Prime factors of 715 are 5 x 11 x 13
Prime factors of 517 are 11 x 47
Prime factors of 656 are 2 x 2 x 2 x 2 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 340, 715, 517, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 715) = 48620
GCD(340, 715) = ( 340 x 715 ) / 48620
= 340 / 715
= 340
Step2:
LCM(5, 517) = 2585
GCD(5, 517) = ( 5 x 517 ) / 2585
= 5 / 517
= 5
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 340, 715, 517, 656 is 1
