GCD of numbers is the greatest common divisor
So, the GCD (400, 270, 491) = 1.
Given numbers are 400, 270, 491
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 270 are 2 x 3 x 3 x 3 x 5
Prime factors of 491 are 491
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 270, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 270) = 10800
GCD(400, 270) = ( 400 x 270 ) / 10800
= 400 / 270
= 400
Step2:
LCM(10, 491) = 4910
GCD(10, 491) = ( 10 x 491 ) / 4910
= 10 / 491
= 10
So, Greatest Common Divisor of 400, 270, 491 is 1
