Given numbers are 400, 397, 265, 851
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 397 are 397
Prime factors of 265 are 5 x 53
Prime factors of 851 are 23 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 397, 265, 851
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 397) = 158800
GCD(400, 397) = ( 400 x 397 ) / 158800
= 400 / 397
= 400
Step2:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
Step3:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
So, Greatest Common Divisor of 400, 397, 265, 851 is 1
