Given numbers are 400, 613, 840, 717
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 613 are 613
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 717 are 3 x 239
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 613, 840, 717
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 613) = 245200
GCD(400, 613) = ( 400 x 613 ) / 245200
= 400 / 613
= 400
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
= 1 / 717
= 1
So, Greatest Common Divisor of 400, 613, 840, 717 is 1
