Given numbers are 105, 400, 851, 257
The list of prime factors of all numbers are
Prime factors of 105 are 3 x 5 x 7
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 851 are 23 x 37
Prime factors of 257 are 257
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 105, 400, 851, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 400) = 8400
GCD(105, 400) = ( 105 x 400 ) / 8400
= 105 / 400
= 105
Step2:
LCM(5, 851) = 4255
GCD(5, 851) = ( 5 x 851 ) / 4255
= 5 / 851
= 5
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 105, 400, 851, 257 is 1
