Prime factors of 689 are 13 x 53
Prime factors of 458 are 2 x 229
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 253, 400, 689, 458
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 400) = 101200
GCD(253, 400) = ( 253 x 400 ) / 101200
= 253 / 400
= 253
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
So, Greatest Common Divisor of 253, 400, 689, 458 is 1
